Just Signed for my Second Credit Card with a Credit Union, Is it any good?

So my first credit card is was a Capital One Platinum Secured Card and after 8 months of having it they upgraded it to a normal Platinum card that I, at most, have less than $45 on it at a time. I used to have a car payment as my second credit account, but it pissed me off so much I paid it off early with 0 fees since I negotiated that in. Through credit karma help, I knew I needed a second card that I'm only gonna use for gas (I'm not exactly decided). APR to my understanding on their website says about 11% or about 17% on the paperwork which I know is good compared to some other cards I looked at since it seems like the average is 26-27%. No annual fees, and no cash advance fees and such which I wouldn't use anyway. I'm not sure about benefits which is something I should've asked but by the time I got to applying I had been awake for 24 hrs. I just wanted to get the opinion of people who have done this a bit, I've stayed pretty dormant with my financials and I want to start ramping up to enjoy life more.
