I thought this choice would have been easy but I find the older triple changers much better than these modern ones. Eventually I chose Animated Blitzwing.

Blitzwing because I love my SD anything and that Tank mode is certainly within that range. For those in the know, it looks a lot like an Advance Wars tank. The robot mode is the biggest clincher though. It's well proportioned (stylistically) and solid. The real downer is the jet mode. Those tank treads are just awful on the undercarriage. I keep thinking how they could have engineered the treads to become more flush towards the back but ah well.

Tankor is just meh in all modes. While at least believeable in both vehicle modes out of the three with their well proportioned angles and features, they all just have too much gaps and holes. Those short arms in robot mode was the biggest downer for me.

Astrotrain has an excellent shuttle alt. Very nicely accurate and proportioned, but the train mode is awful and his robot mode also suffers short arm syndrome.

In the end these 3 aren't exactly excellent figures. Too much sacrifices made in each mode with a preference for one mode. Saying that I still commend the engineers for doing their best though. Perhaps a Voyager or Ultra sized Triple Changer next for the Universe line?
