The Kemper is amazing, great sound and well built.
I've only used it at home at the moment for recording. The Kemper comes with great sounds in the box and many more in Rig Exchange. The response while playing is really good in my opinion, not any noticeable delay. Built for the professional player.
And the remote control is also very good and well built. It's heavy, which i like, and stays in place while stomping on it. Not any noticeable delay while changing presets.
I would recommend this product to anyone that wants a great sounding rig. The fact that you can "copy/clone" existing real amps with almost the exact same sound is super cool.
There is so many profiles for purchase on the internet and I believe you can find any amp/profile you want.
Overall, 10/10 for me. A bit pricey but well worth it if you have the money!
