I use my Amex whenever possible. The benefits are numerous:
Extended warranties, easy proof for insurance, great tracking, no limit, no payment games (I pay in full every month) and they give rewards points. The points aren't exactly cash back but I've never had trouble using them. I recently put a vacation on my Amex and the insurance they offered was cheaper than anywhere else and the coverage is good.
Some retailers hate Amex because it is expensive, so I do use other cards or cash at times.
