In looking at the details, one thing I really think is important is it has two door with vestibules and with at leats a small awning over the doors.  This allows options for keeping things open yet still dry under most rain conditions.

The one things I do not like, but this is common to every tent I have seen, the fly stops a few inches above the ground.  All that water running off the fly will (depending on wind) drip or spalsh on the bottom of the tent body. If one has one's sleeping bag touching that tent body on the inside, it will tend to wick water in (if not right away, it will as the tent ages). make the fly just a few inches longer, and the tent body stays dry.
