Go! For me it might be universe 2.0 Cyclonus. Who's yours? EDIT: Someone asked me to compile the top vote getters. This is by no means comprehensive, but here's a short list for those wondering who's most popular among the community. Cyclonus (Universe 2.0 or RTS) Universe Hound Classics Mirage Classics Seeker Mold RTS/United Jazz HftD Terradive FE Starscream Over 60 bots got votes, and more seem to be coming.
henkei hound and classics mirage are very close for me. think I like the mirage mold just a tiny bit more though, but they are both awesome toys.
Personally, I'm a fan of the Movie Landmine deluxe. There is almost NOTHING you can't do with the generous amount of articulation he has. He even has an almost intentionally easy to remove (and put back on) head to act as dead cannon fodder.
FE Starscream in Takara's colours? WFC Optimus Prime? Animated Rodimus\Sideswipe? Animated Blurr\Cheetor?
Best deluxes: Classics Mirage Classics Skullgrin Classics Wreck-gar BM Jetstorm Animated Cybertron prime ROTF Battle blade bumblebee

Universe Hound, Universe Cyclonus, Universe Prowl mold, Classics Bumblebee, Classics Mirage, Classics/Universe/Generations Seekers... Okay, all of the Classics molds, even Grimlock and Galvatron.
