Much of this is Subjective & varies by "Taste" as you can see from these 2 Opinions & my opinion is My Friedman ASC-10 is vastly superior to the QSC K10 & K12, RCF NX-12SMA that I still have, just relegated the QSCs to my Bass Player & Drummer for Vocal Monitors.
I found FRFR to be terrible for interactive feedback Soloing etc... made me leave the Modeling world & go back to Tube & Amps & Analog Pedals. Getting older & playing smaller venues has driven me back to using a Modeler & the Friedman ASC-10 gives me the feeling back that I'm playing an Amp.
Others have bought ^ sold the Friedman cause it wasn't "Their Thing"
Again, its all very subjective
