I prefer AROS over MorphOS and AmigaOS4 . I never got to chance to try the other two but I'll do that in the future when/if on of them switch to x86. I already have a desktop+laptop and AROS runs on them both so I wouldn't want a third machine.
AROS is nowdays good enough for most things but whenever I need something special that AROS lacks I just restart my PC and selects Windows. So it's not yet my main OS but it's getting real close.
