One thing I noticed is that they are much different in training than in racing. In training the speeds your riding vary much more than in training, and the speed is more often in the middle of the gear range rather than near the top-end. As a result, in training you end up double-shifting (front and rear derailleur at the same time) much more often than in racing due to the small overlap in gears in the middle of the range.
Other than that, microdrive rules: lighter, lower Q and less complicated than triples. I've always had a dislike for triples, hopefully they will be extinct in a few years.
