I've ended up leaning towards my own profiles and di profiles. I found Tilis cablab pack on here for the cab section. One of the cabs sounds exactly like my own favourite marshall 4x12.
The cab makes a huge difference.
I've locked that cab and out of 1000s of profiles have 20 I use, maybe 6 different amps with varying degrees of gain. Some work well with all guitars some with others. I find the kemper very fickle. But after years I've managed to get the tones of my cranked amps at low volumes and via a power amp and my 4x12.
