Want to get a head start (secured card question)

My 341 meeting is Friday July 11.

Nervous but shouldn’t be I’ve been told but still am.

I am currently researching the best secured credit cards to get, to help build credit. I’ve seen good thing about a couple. Discover, capital one being the main 2.

Neither of these companies did I ‘burn’. I do have a car loan thru capital one, that I am keeping during my CHPT7.

Which ones do you prefer? Only looking at no annual fee ones. I’m leaning discover for the rewards but would like some inputs.

For clarity yes I will be waiting til September when I am discharged, but also want a head start so I can get my ducks in a row. Thank you
