Help me find the best all-in-one ethereum and erc20 wallet with an exchange, direct conversions between erc20 tokens, and preferably integration with hardware wallets like Trezor or Ledger

I'm far from new in crypto. But this new world of DEX's, wallets, exchanges, airswaps, etc is too much for anyone.

What is the most trusted all in one place to do everything?

UI/UX should be easy and clean. Sign-up should be simple as well.
