I fully understand that there would be many who don't care for it, but as pretty much solely studio-based player - I would absolutely adore an on-screen editor where you can really see your signal chain.
I think the KPA is a better sounding unit, but I have to admit I was seriously temped to switch to an AxeFX after finally trying one at home for a couple of days recently. I feel like for me, this is the only thing I could possibly want from the unit that I'm not already getting - never felt the need to request anything else in the now-years of everyday use.
