I always judge a VF by the beauty of their fighter mode. It is clear that the VF-0D, VF-4, and VF-17 are winners in this department. They've got a unique silhouette which makes them quite different from one another. Whereas the VF-2SS on the other hand is nothing special. It brings nothing new to the table.
Sure. I'd eventually get one. But I'd place its priority at the very bottom of the list. As mentioned before Yamato wants to flood the market in 2010 with a BUNCH of Macross 7 VF's. I'm fine with that since it's probably more popular than Macross Zero, Macross Flashback, and definitely Macross II.
IMHO the order of release should be:
1. VF-17
2. VF-4
3. VF-0D
4. VF-19
5. VF-2SS
Best looking fighter mode:
1. VF-4
2. VF-17
3. VF-0D
4 VF-19 (YF-19 is boss)
5. VF-2SS
