I would say it's a good choice - I haven't used Trust wallet much, but the thing is do you need a wallet just for Bitcoin or do you want a multicurrency wallet? One small note - if you generate a wallet (seed words) on a computer, and use the same seed to create the same wallet in the mobile version of Electrum, make sure that you are using the official version of Electrum and that you have a clean computer from viruses/malware.

What I want to warn you about is that you are exposed to a double risk if you generate a seed on one device and use it on another.
