Nobody knows the "why" of on-hit being less popular (and it IS less popular: I see five AD Kayles for every one on-hit, and that's a conservative estimate), but if I had to make a wager, I'd say that most people prefer what AD brings to the table.

An AD build brings you mobility (Zeal/PD), AOE, pushing power (wave shredding + tower damage), sustain (lifesteal), and lategame scaling. On-hit loses in all of these categories. Granted, in exchange you get cheap damage, a good transition/midgame, more tankiness, and a bit of extra utility (the flat shred), but that doesn't mean it's what your team actually wants. I almost always find AS/AD to be a superior choice when I am top lane.
