Use this helpful 3x3 grid to understand where OS4/MOS/AROS zealots are coming from when they comment on any combination of the three different systems.
In row major order, they can be summarised thusly:
AmigaOS4 zealots (aka BAFs) perceive AmigaOS4 to be the one true OS due to it's direct lineage from the sacred 3.1 source. Discussion about alternatives is acceptable only after the fact they are not AmigaOS has been established. Conversely, AROS is perceived as a sinister threat, spawn of those that turned to the dark side (x86) only to spread like an unchecked disease to PPC, ARM and now even 68K! Finally, they perceive MorphOS as the wannabe contender that barges into every discussion about AmigaOS4 hawking their jumped up alternative, but alas the blue short ones do not hold the sacred symbols that belong to the one true OS, no matter how much they'd like to lay claim to the throne.
AROS zealots perceive AmigaOS4 as chained to anachronistic, slow hardware that will forever hold it back as time marches on. Hardware that is, like the equivalent mass in gold, astronomically expensive. They perceive AROS as the logical way forward; sexy, free and unrestricted by any notion of which hardware should be used to run it. Finally, they perceive MorphOS to be fundamentally flawed in a similar vein to AmigaOS4 tied to ageing hardware, though at least this ball and chain is available for rather less outlay overall.
MorphOS zealots (aka Smurfs) perceive AmigaOS4 as a wholly inferior product without any positive aspects at all, tied to obsolete, overpriced hardware. Consequently, they are completely unable to understand why anybody would use it, other than through some blind cultish devotion. They perceive AROS as an immature system, far behind the standard they believe MorphOS to have attained and thus aren't unduly concerned about the fact that it runs on even cheaper and far more powerful hardware than their OS of choice. Nor, it seems that the gulf in functionality that is their mantra is closing every day. Finally, they perceive MorphOS as the pinnacle of the Amiga experience, even if it is only fully appreciable on PPC Mac, to which it brings a second chance at life (thus skirting around the obvious observation that it's equally obsolete as the hardware their crimson adversary favours) after the architecture was unceremoniously dumped by apple in favour of x86.
