After a pretty good downpour while camping with the Girl Scouts and a variety of tents, I'll add something I've noticed...
All of the recommended tents pictured above, and my recommended Kelty Grand Canyon, along with other tents I've used or observed over the years indicate one major trait to look for is a fly that extends down far enough to overlap the lower sidewalls (tub).
The upper sidewalls are typically not waterproof, and a surprising number of tents leave part of the upper sidewalls exposed when the fly is on. If you have any amount of rain, you're asking for water intrusion...
As a matter of fact, the fly itself is generally not entirely waterproof, and some water will get driven through the nylon and collect on the underside. Condensation also collects on the underside of the fly. Therefore make sure your tent fly can be guyed out so that it does not touch the tent body (except where it has too, like the pole sleeves).
I'd also echo the recommendation for aluminum poles, even though our Kelty Grand Canyon fiberglass poles are still going strong.
Less poles are easier during setup, but typically more poles mean less flapping in the wind.
Avoid 'cabin' tents and focus on 'dome' tents. Much better in windy conditions.
As mentioned above, more clips make it easier to set up and take down. Ours has short sleeves at the peak, and clips down the walls.
I know that I've given a lot of generalizations, and individual tents may vary, but that's my $0.02.
