I only have the 22S regular, and the things I loathed about it are the easily scratched off paint apps and the fact that the toy gets loose very quickly over time. This annoys the hell out of me. Ever handled a worn down G1 Transformer? That's what it feels like. I did hear that Alto's Tornado Messiah isn't as bad, but nonetheless, there are other things that annoy me. Now mind you, I don't mind the sculpt, but I hate how the shoulder cannot move outwards much from the shoulder armor. Instead, the entire shoulder block moves, which looks weird. The torso connection loosens up, rendering the waist swivel redundant. There are no thigh swivels, making battroid mode articulation disappointing, leaving the gerwalk mode even more so.
The DX VF-27 has more shoulder articulation from the shoulder armor/pads, thigh swivels, and better landing gear, it's a step in the right direction and was designed by FLEX, from Bandai's Hobby Division as opposed to Tamashii, their Collector's Division. A DX VF-25 redesign or all new design by FLEX/Hobby Division would be preferred by me.
