I'm sold on NGK copper plugs. copper is a better conductor that platinum; platinum just lasts longer.
FWIW, some cars do hate certain plugs. saturn S series flat out blow on platinums, only NGKs work well in them.
I just put NGKs in my VUE this year, and am running denso in my MPV.
I would offer that proper gap is very important, no such thing as 'pre-gapped'.
