I have HT prime, I love him. I was just messing with him a bit after watching this video. Size is another factor, 3A prime is gonna dwarf HT prime and down the road you might want to pick up some more of 3A's other G1 figures, I think HT has given-up on Transformers after their Prime efforts kinda blew up in their faces. I don't see 3A jumping ship with their G1 line. Can't wait to see what their Bee/Spike looks like. At the end of the day, I say buy both! HT prime, with a little searching and patience could probably be picked up for almost 200.00 and will always be awesome as a stand alone Prime piece.
