I'd guess that the OP is comparing the base card ($45/yr fee) with the Premier card ($85/yr fee). The main websites for each is not real clear, but if you click on the card details link, it will tell you if you get 5pts/$ spent at Marriotts or just 3 pts/$.

Based on that, I would guess, the real question is will you use either of the cards very much? If you will be staying at Marriotts and using this card, then the extra points your get per $ with the Premier card will probably be worth it. If your getting the card just for the sign-up bonus and then going to through it in the drawer and forget about it, then probaby the lower fee one is better (also I think the base card comes with the annual fee waived for the first year where the Premier card doesn't normally do that.)
