Remember, it isn't about how tall you are, as much as it as what your in-seam is.
I had a Ninja 500 and really liked the bike, but had to do some mods to make it more comfortable (corbin seat, mirror extenders...probably some other things also). But, most riders do some mods to make a bike their own. I now have a 2009 Wee-Strom and love it. Ergo's are great, and it is a wonderful all around bike.
I'm 6' tall, but only have a 31.5" inseam. The Ninja was an easy flat foot. The Wee is a little more of a stretch, but still do-able. Lowering links in various lengths are available. I use my Wee as a daily commuter, general round about, and weekend explorer.
The Wee's have a great reputation and great dependability history. If you can find one in your range, I would snap it up. The Versys also has great dependability and history. I test rode one and it just wasn't right for me, but they are very popular. All the bikes you have mentioned would be great. Good luck!
