It's also because Bumblebee Optimus Prime has a more complete looking truck mode. ROTB OP's truck mode is fairly ordinary and pretty rubbish from behind, whereas Bumblebee OP's truck mode only has a gap in front of the trailer hitch, but otherwise looks fairly complete, even including the sleeper compartment. ROTB OP is definitely the superior action figure, but Bumblebee OP remains the superior truck toy. And both figures have their pros and cons in achieving this; as you said, 'Bee OP is chunkier as a result of being the better truck while ROTB OP has a less realistic looking truck mode as a result of being a better looking and more poseable robot.

And while this doesn't personally bother me, some people might take issue with ROTB Voyager Optimus Prime being a rather small Voyager.

As you can see, ROTB Optimus Prime is the smallest of the Voyager Movie OPs. He is still taller than Deluxe Protoform OP, but shorter than the other Voyagers; pretty much midway between the typical height of a Deluxe vs Voyager. Of course, his engineering and poseability is far above the other Voyagers, which is where the budget has obviously been shifted towards, but at the cost of the toy's size.

Again, not something that personally bugs me; but then again, I'm the kind of person who's perfectly happy with the size of my G1 and Titans Return Blasters (I skipped Kingdom/Legacy Blaster; Legacy Twincast is the only version of that mould that I have). But I know that scale matters more to a lot of other fans, so I can see how ROTB OP's size might be a point of contention for some people.
