Personally, I don't think that "right" or "wrong" is nearly as important as the emotional experience of bonding or not bonding with your gear, and sometimes it really is difficult to shake an initial bad feeling, no matter who else is loving the very thing that doesn't work for you.
Most important thing in the world and in my opinion what it all boils down too. If the sound makes me feel something, makes me want to play and pushes my creativity I don't care if it's a 5 watt Blackstar, a Marshall handwire or NI Guitar Rig it doesn't matter to me, it's about the attachment to the sound.....although let's face it if our favourite artists donated all there gear to us we still would not be happy because we are guitarists, we would want the recording desk and racks the sound was recorded though, we would want the person who mixed it and a time machine to go back to the year the album was recorded because there was less pollution and somehow that helped with the micing technique.
I love my Kemper and it has served me well in the short time I have had it but I am yet to gig with it hence why I sold everything but my JVM. I have no doubt it will blow me away live and provide me with the feel I need but I remember turning on that JVM and I just couldn't stop playing with zero tweaking but after a while the Kemper had the same effect.
It's the same as buying profiles. You will waste money finding a Profiler who gives you what you want. I have bought from around 8 different highly rated profilers and find I always return to one particular person. Even the same amp profiled by different people can go from tinny to full sounding just based on the profilers technique......its just pure opinion.
As a side note the forum over the last month or so has become extremely defensive and posts for help are becoming sidetracked by people's opinions, and frustrations rather than providing help. We are close to Line6 forum replies of "RTFM" "do you know what the search function is for" and "you don't know what you are doing". The attitude of some new members, not referring to this post, and the tone and nature of the responses of older members have made me inhale deeply at times and I have thought "if I need help the forum is not the place to go".
We are here to share our experiences, help each other achieve the tones we crave and as equally important provide a place where people feel comfortable posting for help knowing they will not be ridiculed or their post ending up 18 pages long with no actual helpful reply to the post.
This is just my opinion and if I have misinterpreted the replies then my apologies but I'm hoping the OP finds his sound and comes back to contribute to the forum.
Good luck mate and hope the FRFR gives you what you want. I have never tried the Kemper though a cab as frankly I don't want to like it and have to carry a cab with me lol.
