Wide range 10 speed cassettes shine the best when you run them with smaller cranks. I converted a 30-39-50 triple with a 12-27 cassette to a 34-46 double with an 11-32. Nearly all the wide MTB cassettes have an 11-tooth cog, which makes perfect sense when you take into account MTB chainring sizes. A 46x11 combo is a taller gear than the 50x12 I had before. Not many average joes are pushing a 50x11 (I do occasionally on my race bike, but that's it), and only very strong cyclists on race-ready bikes are ever pushing 52x11 (or taller!).
I never liked the 34-50 compact double. The wide gap made me avoid shifting the front because it was unpleasant. But the 10 speed 11-32 allowed me to duplicate the triple's range, tighten up my crankset to an appropriate jump between chainrings, and simplify the entire system.
Gearing I run:
Race bike: 36-50; custom built 11-27 cassette in back.
Cross/travel bike: 34-46; 11-32 cassette. (Would have gone 11-30, but couldn't find one)
Cross/utility/commuter: 30-39-50; 12-32 in back. That one is purpose built. The 50t ring is useful on the road, but when I race it in cross season I operate it like a 39t single chainring setup (I never shift the front) and the 12-32 range gives me the ability to stay on the 39t. Why keep the triple, you ask? So I can use it for other things, plus a bash-guard and chain-keeper is hardly different in weight than a chainring and front derailer.
