in my experience with profiling with the kemper, the low-end is indeed really tricky to get profiled accurately. at least on many high gain amps i've tried. does it sound/feel great, though? absolutely.
if you're looking to recreate the tone of a mic'ed amp, the kemper works VERY well. even though it's not an exact copy of the original amp, i'd like to see those differences in dynamics and low-end stand out in a full mix.
the last whitechapel is all kemper (5150iii through recto cab) and sounds way better than any axefx metal tone i've heard before. at least for that kind of music. i've heard some very good axefx tones, too.
