I don't see what (real) problems any of them actually solve? Most of those are L1 blockchains and their only innovation is more tps but with plenty of other downsides like centralization. None of which are being used except to create more L2 shitcons. Development of L2 solutions like lightning completely negate any benefits of those tokens.
Ethereum has smart contracts but that's only opened the door to more scamcoins. Bitcoin can be programmed in a similar fashion with the onset of covenants. But do we really need it? Is it solving a real world problem or just coming up with an unnecessary albiet novel use case?
Ecash is a precursor implementation of bitcoin as I understand it. But it utilizes a mint which I struggle with. Seems like an inferior bitcoin to me.
Montero has privacy so I give you that.
