here's a video with a good comparison between FE and RID Deluxe Cliffjumper:

but from what I've seen in pics, the RID deluxes are smaller. And looking at the pics of BB, you can see at the shoulders were the FE version actually uses the wheels like it's supposed to, where as the shoulders are just molded onto the figure for the RID version. in his review peaugh talks about the RID deluxe Cliffjumper uses more "fake" parts instead of the actual pieces from the car mode and the same looks to be for RID BB just judging solely from pics. The chest area on the FE BB is also more accurate that the RID version despite the fact that it does have an Autobot logo on it. The only benefit I see to RID BB is the dual arm cannons where as the RID version only has one
and here's his review of RID Voyager Optmius with a comparison to the FE version. I do agree with the RID prime being a fun figure and having a more accurate truck mode but I do disagree about 2 things in his review though. 1) the shins plug in just fine and stay in pretty snugglely on my RID Optimus so he may of just got a loose one. 2) I know it's weird to judge someone on how they transformer these, but I will say that it's a much smoother transformation if you for the back or "cape" first then do the legs, followed by the arms and what not. a minor nit to an overall good review. I always watch his reviews and they're good but those are 2 things that bothered me a bit about this one
