nice, the Minimus look great. HOWEVER, back to the topic at hand.
I've never had the 3.0's, those will be hard to find anyways. The 5.0's were really great, even the later versions.
OK so in the picture: the light blue are an earlier version of 5.0. These are good because they are very minimal... not much heel, not much cushioning, no arch support. BUT - these are just ugly to wear, and your pinky toe (if you have big feet like me) will stick out visibly on the side.
The black+red in the picture are a later version of 5.0's. I think they are V4. They are good like the earlier version. They added a tiny bit of heel cushioning, but they are much more stylish to wear.
The best one's made IMO, which I have, are the Nike 7.0's with the strap (shown in pic). They are stylish, they fit SNUG, you have lateral support in case you want to play basketball in them/do other shit other than running + lifting. And the arch support is very minimal, along with the heel rise and cushioning.
The Nike Run+ (not shown in the pic, don't have them) or whatever is shit. Too much arch support/cushioning/high heel etc.
