I got the citi dividend plat a few months ago when I was looking for a bt card that would have rewards also. As soon as I got it, I realized that the rewards weren't really suiting for me and Forward was much better based on my spending habits. They would NOT PC, which really pissed me off because it was a brand new card that hadn't even been used. They don't seem very CS oriented IMO. I'm not thrilled with the upcoming rewards categories, and as someone else pointEd out, you have to wait till you have $50 in rewards to cash out. That's $5k in purchases, based on 1% rewards. Anyway, I'd compare forward to dividend plat and see which suits your needs best. If I were going to get one today from citi, I'd get forward. Amazon, restaurants, books, movies, great categories IMO.

Unfortunately, The Dividend's rewards are rather lackluster. The rotating categories are nearly always useless...I think the only one I really used was they once had the 5% back for fitness memberships, so I set my gym fees to go directly through it. Other than that, I've been somewhat disappointed with the rewards. I LOVE Citi though, so I would say if you want to start a relationship with them, it's a good idea. I got the Forward a couple months after the Dividend, and I find it more useful, especially the 5x points on fast food which was, at the time, a staple in a college kid's diet.
I was just approved for the ThankYou Preferred card yesterday and two soft pull CLI's, so Citi will take care of you if you treat them well.
For cash back, my Freedom and Discover More (soon to be IT) are way better, though. Unfortunately, Chase and Discover are my lowest limits by far, meanwhile the Citi ones are among my highest, so I use them a lot more. It's up to you!
