I've had all three. The 200 lm. was fine, I used one at work for over year...like Grijon said, it was throwy and it seems like it was a blueish tint, but I can't remember because I lost the light a few years ago. I've used a 320 G2X Pro for a couple of years at work and I like it much better than the 200 lm...great combo of throw and spill, excellent tint and bright enough to light up anything within 50-75 yrds (just guessing). It's the best light I've ever carried at work. When I thought I had lost the G2X, I bought a 600 lm. model 6PX Pro to replace it. I didn't use it much before I found where I dropped the G2X, but I didn't like it as well...sometimes the brightest light isn't the best one for the job. It was way to bright for my use, I'd get a lot of back flash, for lack of a better word, meaning I would use it in a close quarters situations and it reflected off of objects back in my eyes and blinded me. I then used it as my bigger, "outdoor" light on weekends on my gf's farm a couple of times, but it didn't throw like my Fury, plus the head gets really hot fairly quick...way hotter than the Fury, which makes sense considering how much more surface area the Fury head has over the 6PX. I'd just got it sitting in the truck in case I need it, but I doubt I would buy it if I had to do it over again. The 320 is the way to go IMO, but I'm sure others may disagree.
