If you are new to crypto currency mining and cant decide where to start then the choice between an ASIC miner or a GPU miner will depend on a variety of factors, including the specific cryptocurrency that you are looking to mine, the mining difficulty, your budget and the price for electricity!
Both Asics and GPUs have cons and pros:
Pros of ASICs:
  • High hash rate: ASICs are specifically designed to mine a particular cryptocurrency and can perform the task much faster and more efficiently than general-purpose devices like GPUs.
Cons of ASICs:
  • Expensive: ASICs can be expensive to purchase and may not be cost-effective for small-scale miners.
  • Limited flexibility: ASICs can only be used to mine a specific cryptocurrency and are not suitable for mining other types of coins.
  • Noise and heat: ASICs can generate a lot of noise and heat, which may not be suitable for home use.
  • power consumption
Pros of GPUs:
  • Flexibility: GPUs can be used to mine a wide variety of cryptocurrencies and are generally more affordable than ASICs.
  • Lower noise and heat: GPU miners generate less noise and heat compared to ASIC miners, which makes them more suitable for home use.
  • You can resell your miner into parts to gamers when are u done with it.
Cons of GPUs:
  • Lower hash rate: GPUs are general-purpose devices and not specifically designed for mining, which means they may not perform as well as ASICs when it comes to mining a specific cryptocurrency.
If you are looking for the most powerful miner available, then ASIC are the way to go. However, if you want a more affordable miner that consumes less energy, then GPU are a better option. It really comes down to what you are looking for.
ASIC (Application-Specific Integrated Circuit) miners are specialized hardware designed specifically for mining a specific cryptocurrency. They are typically more powerful than GPU miners, and can offer a higher hash rate (the speed at which the miner can solve the complex mathematical puzzles required to validate transactions on the blockchain) for a given power consumption. They also tend to be more expensive than GPU miners.
GPU (Graphics Processing Unit) miners, on the other hand, are general-purpose hardware that can be used to mine a variety of cryptocurrencies. They are typically less expensive than ASIC miners, and are more versatile as they can be used to mine multiple coins, but they generally have a lower hash rate and higher power consumption than ASIC miners.
The coin you want to mine also play a huge role in the decision. For example, Bitcoin mining is mainly done with ASIC miners, as the mining difficulty is very high and requires specialized hardware.
In summary, if you want to mine a specific coin, and want to get the best performance, an ASIC miner would be the best choice. But if you want to mine multiple coins and want a more versatile and budget-friendly option, then a GPU miner might be a better choice. Gpu is more suitable for mining in home environment rather then Asics, where asics is more suitable for industrial environment! 
It’s worth noting that the mining industry is constantly evolving with new ASIC miners being released and old ones becoming obsolete, so it’s hard to say which is the best available on the market right now. However, as of my knowledge cutoff, some of the most popular and powerful ASIC miners currently available include:
 
  1. Bitmain Antminer S19 ProXP: This ASIC miner is designed for mining SHA-256 cryptocurrencies, such as Bitcoin and Bitcoin Cash, and has a hash rate of 110 TH/s with a power consumption of 3250 W.
  2. MicroBT WhatsMiner M50  This ASIC miner is designed for mining SHA-256 cryptocurrencies, such as Bitcoin and Bitcoin Cash, and has a hash rate of 112 TH/s with a power consumption of 3250 W.
3. The AVALONminer 1246 is a newer ASIC miner that has recently been released and is designed specifically for mining the SHA-256 algorithm-based cryptocurrencies. It has a hash rate of 90 TH/s and a power consumption of 3250W, which is considered to be quite efficient for an ASIC miner.
4. The WhatsMiner M32 is an ASIC miner designed for mining SHA-256 based cryptocurrencies, such as Bitcoin and Bitcoin Cash. It has a high hash rate of 110 TH/s and a power consumption of 3300W
 
The best GPU miner will depend on the specific cryptocurrency that you are looking to mine, as different cryptocurrencies have different requirements and algorithms. However, some of the most popular and powerful GPU miners currently available include:
  1. NVIDIA GeForce RTX 3090: This is currently considered one of the most powerful consumer GPUs available on the market, and is well-suited for mining a variety of cryptocurrencies, including Ethereum.
  2. AMD Radeon RX 6800 XT: Another popular choice for GPU mining, the Radeon RX 6800 XT has a high hash rate and low power consumption, making it a great option for mining a variety of cryptocurrencies.
  3. NVIDIA GeForce GTX 1080 Ti: This GPU is considered one of the best value-for-money options for mining, as it offers a high hash rate at a relatively low cost.
  4. AMD Radeon RX 5700: is a budget-friendly option that can still mine many cryptocurrencies well.
It is important to note that the mining difficulty and network hash rate of a cryptocurrency can change over time, which can affect the mining profitability and the best GPU miner to use. Additionally, the cost of electricity, cooling, and the cost of the GPU itself should be taken into account when determining the profitability of mining.
So all in all if you have cheap electricity available and good amount of budget why not invest into crypto currency mining as cryptocurrency is a relatively new technology, and its future is not yet certain. Cryptocurrency has the potential to revolutionize the way we think about and use money, and it has already shown to be a disruptive force in the financial industry. However, there are still many challenges and uncertainties that need to be addressed, such as regulatory issues, security concerns, and scalability limitations.
Many experts believe that cryptocurrency has the potential to become a widely accepted form of currency in the future, as more and more businesses and organizations begin to accept it as payment. Additionally, the use of blockchain technology which is the underlying technology of most cryptocurrencies, has the potential to revolutionize various industries such as supply chain management, voting systems, and real estate.
On the other hand, there are also experts that have a more cautious view on the future of cryptocurrency, highlighting the challenges and risks associated with this new technology. It’s worth noting that the cryptocurrency market is highly volatile and the value of cryptocurrencies can fluctuate greatly in a short period of time.
