I have zero experience of either, but the QCon Pro G2 looks more promising than Pro X since it has an overlay for Sonar included, i.e. one can assume it´s supported. Another + is that it´s cheaper.
Sonar/CbB wasn´t even mentioned among Pro X´s supported DAW:s.
I.e. I´d look for reviews of the Pro G2 instead.

The
QCon Pro G2 sells retail for about $80 more than the
Behringer X Touch The G2 is a totally redesigned unit from the original less the cool meter bridge, too bad about that, but that's a good indication that the firmware is newer(?), but still only has LIMITED support FOR MCU and HUI which is another TWO too bads.
However that doesn't make it a bad unit pre se, just one that's designed and destined to become obsolete much sooner, although I don't see anyone dropping support for MCU protocol any time soon.
Behringer's flashable firmware has been around for a while, and has had new features and functionality added thru the years, and all deliver rock solid performance and expected results.
The X Touch is built like a tank, has fast, quiet, responsive, and very pro grade tactile touch sensitive 100mm ALPS faders.
And most importantly for a MCU protocol based DAW controller the X Touch has the exact control functions as does the original Mackie. All buttons and rotaries are labeled and function identically to the original Mackie which was designed and built using the very open source friendly Apple Logic DAW. Hence the need for Overlays for use in other DAWs.
The QCon was designed based on the not so or as much open source friendly Steinberg family of DAWs, and so does not have exact open source control support.
The QCon has no dedicated "encoder assignment" buttons that give one button instant access to Track, Pan, EQ, sends, audio plugins, and MIDI instrument control.
The QCon has no dedicated "modifier" buttons M1-M4. These are used for a whole host and set list of user defined and customized functionality. (See Mackie Control user manual for details)
No dedicated automation read, write, touch, latch or
No dedicated "Control Group" buttons Track, Buss, Main, Save, Undo, Redo.
WITHOUT THESE TYPICAL DEDICATED CONTROLS ON THE CONTROL SURFACE UNIT ITSELF, YOU DO NOT HAVE THE COMPLETE FULL SUPPORT, BENEFITS OF CONTROL, ACCESS, AND FUNCTIONALITY OF MACKIE UNIVERSAL CONTROL PROTOCOL.
What is very commonly known as MCU.
While the QCon does come with multiple overlays including one for SONAR and the X Touch does not, the QCon only has one USB connection and 2 1/4" foot controller jacks, it doesn't offer nearly as much present and future expandability options as does the X Touch with it's extra Ethernet, standard 5 pin dyn MIDI, and 2 extra USB hub/ports and individual scribble strips above each channel.
Believe me, you will really appreciate the extra back panel connectivity IMMEDIATLY.
Getting and making an overlay template for the X Touch for SONAR/ CbB is very easy to get. Here in this forum and on Behringer's X Touch user forum.
Ask, and I'll be happy to send you one vis email in .PDF format free of charge.
And so last but not least, ANYONE in this forum or the thousands to millions of other users elsewhere who has EVER used and understood Mackie or X Touch can help you out, troubleshoot, and give you advice concerning these nearly identical, tried & true proven with track records, and truly world class universal DAW controllers.
Or if you prefer to try and reinvent the wheel with a QCon as the new top dawg maybe, maaaaybeee (?) Have fun trying..
