I mean Bitcoin Cash is a clear example here. Pretty much the same protocol, just the block size is bigger. Other then that, I think most use some more ASIC resistant PoW by now, but there is probably some more with SHA256 PoW.
I would agree with this, while Bitcoin creates by Satoshi another Bitcoin Cash was started by Bitcoin miners and developers equally concerned with the future of the cryptocurrency, and its ability to scale effectively. They claim Bitcoin Cash has implemented an increased block size of 8mb, to accelerate the verification process, with an adjustable level of difficulty to ensure the chain’s survival and transaction verification speed, regardless of the number of miners supporting it.
