I've got one of each and I don't think so.

I guess that it's possible to imagine somebody using the big/big with a triple but I certainly never do. I can't even imagine anybody ever using the granny ring with any but the largest 2 or 3 rear cogs. I do use my middle chainring across the entire rear cassette.

Shifting wise, 34 to 50 is a pretty big change. Mine shifts fine but certainly no better than 30 to 42 with my triple.

FWIW, I think that the biggest drawback of a compact double has to do with the flat road gears. If your favorite flat road gear turns out to be near either end of the cassette you're going to hate a compact double. If you basically only use the small chainring for climbing hills, a compact double is great because you won't find yourself in a lot of situations where you need to shift both derailleurs at the same time.
