It is true that you cannot change the address on a trustwallet unless you are going to create a new wallet with a new seed phrase but metamask supports multiple wallet addresses using a single seedphrase which is nearly identical to a BTC wallet except that it does not display the total balance on all wallet addresses that include the phrase single seed. I think it depends on the user experience on the trust wallet.

From my own experience with trust wallets, I can say it is very secure as I have never been hacked, had my wallet opened, or any other unpleasant situations using Trust wallets. Others may have a different experience.

But do one thing right if you protect yourself with a trust wallet or some other wallet and you are disciplined you have nothing to worry about. I've been using TW for over a year now and everything is fine, no issues or complaints for me. It's one of the trading apps I use. I don't know if it's going to be naughty tomorrow but so far so good so far.
