A question is how good they're dealing with open type fonts
(as opposed to 'plain old original' TTFs). Without glyph substitutions
and other smart rendering features offered by OT extenions, it's not
so useful for the rendering of complex scripts (various Indic scripts,
South East Asian scripts - Thai, Lao, Burmese, and the like - , Hebrew,
Arabic, Syriac and Korean, etc ). I know Open Type fonts are not just
MS and Apple's but Adobe also participated in it. However, I'm not sure
whether Adobe is as much committed to supporting those complex scripts
as MS and Apple appear to be.
As for some PS engines you mentioned, I don't think all of them
(esp. gs 4.x) have the (smart rendering/complex script rendering)
capabilities I'm talking about. Even for OCF (original composite font
used for CJK rendering before CID-keyed fonts came to the scene)),
let alone CJK TTF and CIDkeyed font support, I remember having to apply
various patches made in Japan to gs 5.x to make it work (better) with
them. Now at 7.x, I believe GS has incorporated most of those patches,
but I don't know yet how good it is with 'interpreting' OT extensions.
