I've recanted on my initial misgivings. Cybertron Prime for me. Jaydisc showed me I wasn't transforming mine right at all. 'Twas more complicated than I actually expected. I think the Battle-damage is the determinative factor for me. It works better on Megatron but the BD Prime is not as visually appealing.

I like the arms on Cybertron more too b/c he's can hold the axe in both hands simultaneously. A first for TFs and the range of poses that opens up = hours of fun.

As Jaydisc mentioned today, the major annoyance is that the axes aren't the same size for the fist holes. I would love to use that BD axe for both.
