In some other forums (TGP, TGF, ..) it's a commonly accepted truth that Kemper is old, sucks and sounds like a cocked wah, Tonex and NAM are way more accurate and QC is kinda acceptable.
Well I got a tonex and the cab/IR part as well as the effects are a joke. Amp model is nice but tends to get bright/thin when used live. NAM is cool, but laptop on stage? It works rather well with Gig Performer but I'm not gonna gig with my Mac.
People just seem to need a scapegoat and null test results give them justification. It's easy to bitch about something you haven't used ever or at least in years. I'm pretty confident that anyone who has seriously worked with a Kemper in the last 5 years will prefer it to Tonex, QC or any of the Chinese contenders. And if you have spent the time to get your head around working with Scenes on Helix or Fractal, because their switching lag is 1s+, you know how easy to use a Kemper is in comparison.
There's a lot of opinionated, uneducated hot air in the internet. Unfortunately it leads peoples' wallets to some extend.
