There are several places to read reviews although alot of the sites are biased due to referrals etc, not that nerdwallet is pushing one card or another put other sites like pointsguy, etc. certainly can be. I wouldnt use CreditKarma either as they get paid for each approval/app of a card and push certain cards and use vantage scores vs. ficos. Honestly forums like this and others out though such as Doctor of Credit (blog) along with some others are good resources of research.
Look at this post. He does a VERY good job on best card for most things. It will have a good nights digesting for you to engulf it all
