I'd happily buy a Kemper or other modeller without a front panel. As long as you have editing via a computer, phone or iPad it would be fine. Also I wouldn't have to drag a 3u rack around when travelling.I'm not sure I get the UI issue. Are we talking about front panel knob turning?
I have Axe Edit open all the time. No need to use the front plate at all.
Also, we use the 108s at rehearsal for the whole band. They work pretty great actually.
