I really like my card and the bennies and service. So I've used it for everything except Marriott since I got it.
The downside to using it for everything, is that last week there was fraud. Citi tried calling then texted me right away so we were able to nip it in the bud. However, now I'll have to go thru the hassle of resetting all the automatic payments that go to the card. I've had about 5 other Citi cards closed, but they were all for breaches. I think this was the first actual fraud.
