Both miners that you look works on SHA-256 algo so you can mine only coins that use SHA-256 nothing else.
I have some GPUS that can be sold pretty well and i think this is the right time to do that.
My plan is to sell my ETH miners and to invest in BTC miners.
BTC miner pros :
1. Next bitcoin halving will be in 2024 so I will have at least 3 years to mine btc on the same level as it's mined today.
2. My prediction is that BTC price will grow much bigger than now, maybe not next year but after that I'm sure will reach new record.
3. People trust BTC, there's no some big algo changes everything will be the same.
4. I have "host" in Ukraine that will run my machines for 80% less cost of electricity. They have methods to cheat the El. meters

BTC Miner cons :
They take much more energy, if ETH miner is 850W then btc miner will need something around 3.5 KW to have the same revenue (talking for today's price), so if you buy a big number of machines you will need industrial power to run them.
Some of these miners have a working temperature of more than 80°C so you need to cool them because chips burn easily.
BTC miners can mine only coins that work on SHA-256 algo so it's impossible to change firmware and mine other coins.
