I had a well stocked musicstore bassroom for an afternoon to myself to check out for myself what you guys have been raving about 
First, the usual caveats, all IMHO and not in a live gig setting but a solo setting. And I'm nowhere as good in describing sound with words like KJung....
The purpose of this exercise was twofold - not just to check out the current crop of micro heads, but also to find out if my trusty Aguilar GS210 is outdated by comparing it to a GenzBenz Neox 210.
I swapped speakers for every head repeatedly and found KJung to be right again, its all in the mix and match
So, some quick conclusions and some pictures:
GS210
strong, deep lows, attenuated upper mids, bright top, good carry size, but heavy. Did I mention its heavy? I mean HEAVY!
Neox 210
tight bass, definitely less happening down there, where it counts for some the most, prominent mids and upper mids, similiar top, Handling much lighter, easy tilt back rollers, but larger, bit awkward to carry.
In a studio setting the GS210 is much more pleasing, I suppose in a live setting the Neox210 will be better suited. What's the better cab depends very much on the head used and your application. For me, I was quite happy to take my GS210 back home, no regrets, good cab for my needs.
Glockenklang Soul II
my up to now sound reference, it's still exceptionally neutral and all, but to be honest, I never felt the need to jump back to this head for some a/b-ing after testing some of the others. Sound is just too polite for me...
Tecamp Puma 500
soundwise in the same camp as the Soul II with a fairly wide voicing and warm bottom. Better suited to the Neox than the GS210.
GenzBenz Suttle Max 12
WOW !
I liked the FET channel much better than the tube channel, but its good fun for nice fingerstyle. The variable LF Boost of the Global Signal Shape is a great tool, it just acts as agedhorse explained as variable hi-pass filter. That made it an great match for the GS210 to flexibly tame those lows. A much better match than to the Neox210
Markbass LMTube
turned from SS to Tube and back and inbetween... nice enough, but no wow here for me... had high hopes, but SS not fast enough and tube not tubey enough
Markbass F500
WOW !
Pops are intoxicatingly fast and snappy, very wide voicing, VLE and VPF are very useful, powerful EQ. Could nicely tame the lows on the GS and the (upper) mids on the Neox.
TC RH450
due to the controversy about this product line, I was really curious... great features, I like the presets, the stereo headphone out, the tuner, nice enough compressor, but not really a compressor person myself, the tube emulation is ok i guess, but, But, BUT, BUTT I hated the tone
no amount of knob twiddling from me or the stores attendants got me for instance anywhere near the SMax12 FET channel or the F500. Maybe I was fatigued by then and couldn't give it a fair shake or am just too dumb, dunno - it just reminds me too much of my Bod XT setup. The RH450 offers nothing really new for me, but it does it of course in a really nice and stylish package.
It's got a better resolution than my BODxt/KME setup due to the undoubtedly better components and technology, but it has that ever so slight lifeless and artificial sound which I'm unfortunately so familiar with.
It's very difficult to describe - jumping between the Shuttle FET and the RH450, the Shuttle feels more alive.
Enough of that, for more rants, see my BOD xt threads...
Conclusion:
For me it would be this. My sincere congratulations to agedhorse and the GB product development team, that's one nice amp !!!
but could be also quite happy with this:
/rant over... carry on...
