Mine would have to be Leader Megatron. An awesome looking alt mode, solid robot mode and I'm a sucker for lights and sounds. Close second and third are Voyager Grimlock and Wreck-gar. I just love both characters in the show and I thought both of their toys were pretty darn awesome. Wreck-Gar being a garbage truck just makes too much sense, and his face sculpt resembles Weird Al, How cool is that? Grimlock's lock-jaw design really suits the character and I love the mostly silver, red, and gold color scheme on him. Very sharp. What's yours and why?
