I have been slowly coming over to this way of thinking, that I should actually use that thing and let cadence be my guide, instead of going up hills in a low cadence.
What I dislike about the triple (or at least my triple) is the location of the crossover from the big to middle ring. Right at 20 mphish at high 90s cadence, with only one gear of overlap, and no trim. It's a busy area, lots of chain ring shifting. That is why the next bike will likely be a double.
