...platinum version only.
... Wait i dont have the platinu... *Procedes to check disk*
ok, so that clears everything up for me
So to conclude, the best version is as orch said the platinum ntsc, or pal version.
As for the 100% definition i think it should be all skillpoints, goldbolts, missions and items. Not getting all the weapons, as that would just be very boring bolt grinding, and that allows people to select what weapons they would rather get.
I dont see any reason to skip raritanium Espesially now that we have Cyprys' skip for it.
