Well, this is a debate I've made before, upon who plays the "better" Prime. I like Cullen's version the most, but Gary Chalk very close him in my opinion. Some people have said that Chalk plays a better Primal the Prime, but I think otherwise. Peter Cullen's voice is more noble and "older". Gary Chalk's voice is more commanding and vocal. Neil Kaplan is my least favorite voice of Prime. He possessed neither in his impression. So who do you think sounds better as Prime? Peter Cullen - the voice of G1 and Movie Prime. Or Gary Chalk - the voice of Optimus Primal and A/E/C Optimus Prime. NOTE: Sorry that I spelled "your" wrong in this thread's name.
