Well, that's a difficult question, as taste varies widely from user to user.
Normally I follow the discussions on the Rig Exchange sub- forum and make my mind up about a profile later on if I feel like it and if I think Something Sounds promising..
It can be hard to keep up (and will inevitably be near impossible in the future with more and more profiles floating around) but in the Kemper world it's more about quality anyway, not quantity of profiles.
It is like with real amplifiers: you fall in love with a profile and just play.
It was one of the factory profiles: AC Normal Drive.
A few days ago I fell in love with a user profile, rmpacheco's profile of a Morgan AC20 which is incredibly good.

Some very good ones in that mix.
Thanks.
I also tried one that Radley made, and it was excellent!
