I almost exclusively use this module as a 'master' stereo-reverb (it is actually really stereo, I checked) in my rig. It's always patched at the end of the chain and I never turn it off completely, so I think it's safe to say I really like the sound of the reverb on this module.
Whenever I have a busy pattern going on (drums, bass, arps, ...) I use it on a very short setting with the dry/wet knob almost completely turned to dry (so only a little bit of reverb) and it really makes a preformance come to life.
When I have a slower patch (pads or cinematic stuff) I turn it up quite a lot to the point where everything almost drowns in the reverb tail and it still sounds really good. I've gotten compliments before on how good the reverb actually sounds from a guy that genuinely dislikes every digital module out there. To my ear it sounds better than most of the (free/stock) reverb-plugins in my DAW (albeit less tweakable of course).
All of the other effects are decent quality, I've tried them and they sound just great. The delay is really nice and simple and the overdrive/bitredux/... setting (red led) actually sounds a lot like a really overdriven analogue piece of hardware, it surprised me how warm it sounds even though it's completely digital. Don't expect it to add subtle warmth though, it really trashes the sounds you put into it into obliteration, but in the best possible way.
The only 'con' I can think of is in fact that it's a digital module, so sending too much gain into it distorts the sound in a not so great way. Luckily there is a led indicating when the module is clipping so you know when to turn the stuff going into it down.
