I like the Mueller 8-32s that I've used. Very clear, at least on a par with those I've looked through from Nikon. Sorry, haven't looked through a bushnell/burris so can't compare. The T50 prototype beat the Mueller hands down for depth of field. I understand the production T50s aren't as good.
Rangefinding was adequate but depth of field wasn't quite good enough for me past 45 yards. Other people have been fine with theirs. YMMV.

Too many tinker projects, not enough working rifles.
