I had the 11R and had to go through a lot of trouble to get it to sound close to a recorded amp in the mix. And that was only A/B comparing it to my recorded amp.
I had 2 boutiques and 2 well known amps, so for me, as a home player, plugin modelers weren't cutting it. Nor was the 11R.
When I saw video and testimonials about the Kemper, especially CK at NAMM my brother was with me and saying it seemed unbelievable but yet there was the evidence: NAMM and lots of video's showing how it profiles. He was very impressed and said to me "Sell THAT (11R), Buy the Kemper, profile your amps, sell 1/2 your amps". He recommended not even profiling the 11R (I did do a few profiles, one of which seems to be liked on the exchange)
Kemper has changed my entire outlook. I see it as the FIRST time Digital = Analog. When we are fighting off Cyborgs in 2050, we'll point to the Kemper's debut as the starting point!
