So Huobi's mobile light wallet just added TRX and EOS and I checked it out. You can manage your private keys and multi addresses as well. Additionally backup/import features are present and you can instant swap coins through a Changelly integration (that takes off a certain fee tho).
Pretty sweet tool. Here is a review:https://walletinvestor.com/magazine/review-of-the-huobi-multi-chain-light-wallet-after-the-addition-of-eos-and-trx/
I don't want to be sceptical but there has been so many wallet that has the same features like you mentioned. Private key secured, multiple wallet. Even some wallets are more advance in term of security, like two factors authentication, fingerprint, and some more features. Is there some features that makes huobi wallet standout, and better than other wallets out there?
