Yeah I mean like which has the most tokens supported? Like Exodus has a bunch. Trezor for example I hear doesn't support XLM.
I don't think you really need all those altcoins in one wallet and Trezor hardware wallet is supporting XLM Stellar in combination with Exodus and Stellar Account Viewer.
You can check all supported coins on their website:
https://trezor.io/coins/Which ones support swapping Monaro for example?
This swapping exchanges inside wallets are centralized and you depend fully on some third party service provider like changelly or something like that.
I think that both Exodus and Coinomi wallet are supporting Monero for swapping, or you can use open source
Cake Wallet for smartphones that has this feature.
