Maxis match here, mostly. I may make exceptions for certain clothing; I'm not as strict about that (as long as there are no english lettering on them, they don't need that).
But the hair; any hair I download has to be MM. Or at least clay. Preferably with the EA palette too, so I won't have to change their hair color every time I switch the hairstyle.
My sims also kind of have slightly cartoony faces in the first place? That's just my style, so it would feel really weird to tack realistic textures and items onto that. To me, TS4 is just kind of meant to look cartoony.
