POLL: Who's better Costco or Sams Club?

[Miramonti]

I usually get an annual membership for about $50 at sams club and feel that I get my moneys worth during the course of the year with many of the great bargains that they have. But costco just opened up in the area (almost just as close to me) and they have an annual membership also. I've only shopped there a couple times and it seems like the same thing as sams club (I don't know who was first in these warehouse shopping things).

Which do you think is more worth the annual fee, sams club or costco?
