I've played D&D 3.0/3.5 and 4e, and Traveller. I prefer Traveller, it is definitely rules light, I can easily whip up some housrules for it, make new careers, or hey, I can even play in a Darkover campaign (Admit it, Traveller is perfect for playing in MBZ's Darkover).
Meanwhile, in my old D&D group, our game world mas made of several different ones smashed together, there was the WH40K Imperium of Man there (And one guy was a Grey Knight...), our rogue was also a wraith (And we were all second level!), and oh yeah, I had a mecha. From D20 Future. Uhhuh. Traveller is less crazy. Or, rather, it is internally consistent in it's craziness.
Unless we're talking about Canon...
