WOW2 is interesting. There isn't actually too much space on the market for it. You have great filter work of others. FabFilter, Tone2, FXpansion ... and for modulations, nothing beats LFOtool. ...but you get what's happening right after you start the plugin.
Let's cut to the chase. The sound is marvelous. Super-smooth, rich, not over-saturated (unless you want it to be.) Exceptionally good performance in high registers. Resonancy sounds "glassy". Not "whispery" as pretty much any other filter out there, but somehow "glassy". It all is nice and beautiful until you distort it. Then it's of course exact oposite. But again, the distortion is somehow "right". Re-arrangin sonical texture, as distortion should. Really good.
Really interesting modulation system. You have few modulators like gate-triggered ADSR, LFO, step sequencer ... and it's all assignable anywhere you want. I still think that LFOtool is beter for crazy modulations, but, if it needs to be done here, it can be done really quickly with advantage of juicy filters.
Value for money 9/10
I find SugarBytes stuff a bit on expansive side, so I usually look for their stuff seconhanded. With a little transfer fee, I still support the developers, so it doesn't feel that bad to do. They react to trends (I mean ... WOW2's still is heavily Dubstep oriented), but they try to solve us problems. Like with Effectrix, Artillery, or in this things. All their stuff saves you some time. So if you finnancially can, support them, please. :)
