I don't really want to choose between them. Ofc, Ethereum seems more profitable and stable, and people trust it more. But Ethereum Classic has a nice tech and the price is pretty affordable, so I can test some different trading strategies with it, especially for margin trading.
A few times etc gets a big problem and this is not even happening with ethereum. From all of the factors and ethereum will always be superior to ETC. When it comes to the POS and etc still stuck at that level. ETC is not having a good tech and it's an out dated tech
