I have the Copper Spur UL4 and have been very happy with it. It's super light, sets up easily and is stable in the wind. Mine had an unfortunate encounter with one of my cats who sneaked downstairs, but Big Agnes repaired it fee of charge (I only had to pay for shipping).
I've been fortunate that all of my trips with it have been in generally good weather so I cant comment about how well it would hold up in a downpour, but I don't see any reason why it wouldn't perform. I do notice that you get a fair bit of condensation on the inner surface of fly overnight (even with the vents open), but I've always used it with at least 3 people
