They seem to have forgotten the XT250. The WR tends to overshadow it, but I'm quite fond of my overly-simply XT.
I used a DR200 during my MSF class and really liked it a lot. When it came time to buy a bike, I really thought I wanted to get a 650. After sitting on both the XR650L and a KLR650, I realized that I was not ready for a bike that tall or heavy. I'm 6'1" and really felt both of those bikes were too tall in factory configuration. I ended up with my XT instead, saved a couple of grand and have been very, very happy with it. I have problems keeping up with the "big dogs" at times, but I attribute that entirely to my newness to riding off pavement and every trip out find myself getting more comfortable and faster. I do what I like and catch up with them at the next major intersection.
Every once and while I think I want to get a 400 or 650 machine, but honestly, I don't need one. I can haul enough gear on the 250, it makes me travel light and that's a bonus, it keeps my off the interstate, also a bonus, and it's super light and super fun. I think with some suspension work, and building the seat height up some and I'll be really happy with it. If I can find longer cables to raise the bars more than the 1.2" I already have would help a bunch too.
I've been wanting to buy a bigger bike (maybe a Bonneville or another retro standard) but with the pricing on the XT225 where it is for a 3-5 year old bike, I'm honestly considering a second sub-250 for a commuter/corner carver/cruiser. The 225 with taller gearing and it's 6-speed trans would do fine for the 60mph top speed I need.
