I have a triple & a compact double bike - and a lot of times I just like the compact double more because there's less gears to worry about and I really do a better job of spinning & getting into the right gear on the bike.

There's very seldom times when I'm wishing I had more gears, but I do have a spare set of wheels with a bigger cassette on the back for when I know I'm really going somewhere hilly (as in, I haven't really used it yet)
