Which web3 wallet is hard to use nowadays? I don't think ease of use is a good feature to sell. I believe most altcoin users would expect that as the minimum requirement to try a new wallet.

I agree that giving recommendations is hard if we don't know what somebody wants. Even if a new wallet comes there's no urgency to move to the new apps asap, especially if your old wallet runs just fine (plus open source, updated regularly, etc).
