10x10 EZ-Up Brand hands down... I used mine every weekend last year and took it camping several times... It has survived through two pretty crazy storms while camping without a hitch and still looks like new... I personally recommend the tan one vs the other colors because it is a little brighter inside during the evening. When it is very windy I use ratchet tie downs (same kind you would tie stuff down in a truck with)
Good Luck!
