Cybertron Ultra's are bigger than Voyager and smaller than Leader. Mega is a little smaller than Voyager on average. Earlier Ultra from Beast Wars are about Voyager size just to make it all confusing!

I like the color schemes on these two much more than the versions in Cybertron... they look like real planes (unlike the green or purple Jetfire and the scifi looking Wing Saber). I don't have either so I will probably get these.
