Better than the 14:2 mixer? That makes me wonder if you have taken a look at it yourself or watched any reviews at all.
It's nothing like the 14:2 mixer. The 14:2 mixer is having a cheap mixer comparable to a cheap dj mixer that manages some channels and some send and returns.
The SSL console is like having... an SSL console

The master bus compressor is very good on it. Combined with the individual compression per channel, it's just amazing.
Haven't been using another DAW for years, so I wouldn't know exactly how it compares. It wouldn't amaze me if it'd be the most powerful console out there atm.
If you have the time, watch these:
Some shorter stuff:
Using the Mixer - YouTube
Propellerhead - Reason - The Mixer
I'm too big of a Reason fanboy to be objective in any way about it. What I can tell you is that I love
Reason 6. The mixer mostly makes that. We had it in Record before, but than you separately had to have Reason and/or Record. This always seemed stupid. Than for 6, they just jammed those together and that totally made sense. Since 6, I think you can fully look upon Reason as being a DAW. Before that , you had to have Record and Reason and it still missed some features.
With rack extensions around the corner, it's even gonna be better than the step from 5 to 6.
Some complaints about Reason are the Reason sound and the lack of VST support. IMO, Reason sound is something that happens to ppl who don't understand sound engineering and sound synthesis. That's another discussion, been discussed on the forum a lot as well. Even one or two discussions going right now. Just use the search function if you're interested, but tbh, it's a waste of time and time can be spent a lot better watching Garry for instance, giving you some wonderful insights. On the VST support, imo, Reason doesn't need VST support. Reason's always been big on sound design. So quality sounds are more limited to what you can do than what Reason can do.
In short, Reason does it all for me and I wouldn't wanna change!
The mixer is a gem and I can't wait till the fellas at Reason make Reason even better!
