from my own experience I'd say you're comparing the best with the worst. Go with a Trace definately -
bad experience - Ashdown EB115, only had it for about 3 months IIRC, then it crapped out on me at a soundcheck, waited far too long for it to be repaired by soundcontrol, I got it back and it developed the same fault within a week. Soundcontrol replaced it with the newer model, while i was waiting for that to arrive.......
good experience - I bought a second hand 4x19 GP12 smx, a bloody beast. It was (and probably still is) a fantastic, punchy combo, the only reason I sold it was because my band was at the time scaling things down while our drummer quit and the other two were procreating. If circumstances had been different I'd still have it now
