Those two are basically an old version of Monero right before RandomX was implemented IIRC. So ASICS can mine them and if my memory server me correctly - they were largely supported by these ASICS manufacturers.
I am surprised you even found them anymore. Are they still alive? I hope not. They serve no purpose and I guess were only useful to squeeze out some more profit from those ASICS.
Yes, they are still alive. I checked them at CoinGecko. Their prices are close to zero but they are still traded at TradeOgre and Monero Classic even at Gate.io. From your answer I understand that chances for revivals are close zero also. I still hold them because during the fork I had Monero.
