AminoWallet is a wallet capable of signing on the legacy Amino encoding. Amino encoding is still a must-use when signing with Ledger and thus still supported in the chain, but is phased out slowly.
In secret.js AminoWallet is mainly used for testing and should not be used for anything else. The reason is that some Msg types don't support Amino encoding anymore and thus won't work with this wallet (and Ledger). Msgs that do support Amino encoding also must encode with Protobuf, so if a Msg is working as intended with AminoWallet, it'll also work with Wallet.
For reference, even txs that are signed using Amino, are sent to the chain using Protobuf encoding, so inside the chain the tx is converted to Amino in order to verify the signature.
