I had one for a short while, but didn't like it that much. I'd give it 7/10 as a rating - 8/10 if you're not bothered by the excessive amount of knobs and tonal options, which IMO did NOT make it easier to find the sounds you're looking for.
A lot of it though was down to the voicing and the playing feel, so highly subjective. I didn't like that it often felt quite dark and mellow and that I always felt a bit like I was trying to get a bit more edge and definition on rhythm playing. The clips from the bigger heads make it sound brighter and tighter, so that was a surprise. In the rather extreme EQ settings it also had quite a bit of hiss.
Overall though, most people would call it a good sounding amp, especially cleans and soloing. I don't know how it fares in a very loud setting though - since I only had 7 days to return it, I had to make my decision fairly quickly. One thing I also didn't like is that you had to leave that built-in boost "on" most of the time to make it sound proper on high gain, but if you switched to the clean channel it could be too loud/gainy.
The ENGL Ironball I have now is definitely a better-sounding amp - better cleans (and the Ironheart already had very good ones), better metal sounds, less noise. It's more towards the Mesa Rectifier sound though, and of course more expensive. My favs from the small package amps are:
ENGL Ironball
Mesa Rectifier Mini (I would have gotten this one if the ENGL hadn't delivered)
H&K Tubemeister series (this might be the best alternative to the Laney)
Orange Dark Terror (single channel only, but I think a extra EQ pedal in the loop or in front will unleash great sounds)
