<prompt> Human: There are plenty of websites out there that rank credit card offers by rewards, APR, credit score, and so on. But its hard to know what kind of website experience youre in for until you actually obtain a particular card.Personal anecdote: My wife and I just reached the spend required to get the 40k bonus travel points for the Barclay Arrival card, and agreed to stop using it immediately, just because of the website. I originally thought this might become our primary card because it does have good travel rewards, but the way pending and posted transactions are shown on the site is just annoying. It frequently shows purchases as both pending and posted, and on multiple occasions has not shown some transactions -- even as pending -- for multiple days. So were moving back to the Chase Sapphire card. Although the website is a definitely less stylish, it has always been pretty straightforward in terms of how quickly and clearly pending and posted transactions are shown.So how about you, Reddit? Which of your credit cards do you love or hate just because of the website experience?Edit: Great comments so far! Interesting that Amex and Discover have pretty consistent high marks, and there have also been good comments about USAA. Other mainstream banks seem to have more mixed results. Ill update later if things change or other trends emerge from the comments. Keep them coming!  <response>: Im pretty impressed with my AmExs cards app. Makes it easy to track offers and such. Website is average.
