The PS3 version has one less skip (Sylvarant Base skip) which saves a minute, you can't infinite in PS3 version for NG, which makes Sylavarant SUPER slow, you have more cutscenes (that one I'm not really sure, but doesn't really matter for the other points), you can't use Proxy Summon Glitch which helps A LOT in NG and is used in NG+ too.

Oh. Also the movement is slower on PS3. I think that's enough poits to say that: PS3 version is one of the worst version to speedrun this game (still faster than PAL GC though I think).

If you want to see PS3 NG runs however, you should visit the japanese stuff. They tend to do that for some reason.

There are indeed extra cutscenes as well as being unable to enter areas while riding noishe. Also for ng+ randomizer is severely nerfed as you cant mash cast cancel nearly as fast. I believe there are more reasons but I think that pretty much sums it up.

Basically it goes GCN > PS3 > PS2
