This can be re-phrased as a long-term vs short-term question.

BSV and BCH are bitcoin forks with a limited (if any) use case. They have to be seen as short-term coins only. Their volatility  (extreme volatility once Craig Wright gets involved) make them good trading coins. That is all.

Etherum is the pre-eminent smart contract platform with a hugely impressive history and solid roadmap, as well as undeniable use case that could have a big transformative effect on society as a whole. Smart contracts are a winner, the only question is will ETH remain the best smart contract coin? (I think yes, but I'll concede the question can't be settled yet.)
