I used to buy electronics using AMEX cards - good experience. Recently switched to Costco's Citi card due to longevity. I am unsure if this is a good move? Wondering what's been your experience? Also, they all adjusted the features too many times and I am at lost now.

I am posting here to find your experience - and if I should go back to AMEX again - I do not have any AMEX cards with Annual fee?
