Metal bands that use the synth best

Nocturnus and Nightwish are the first two coming to mind here.

I think a lot of newer Power Metal bands have been incorporating too much synth for my personal tastes. Some do use it well, though.

Iron Maiden. Somewhere in Time is a prime example of how synth in metal should sound.
Dream Theater certainly
Queensryche
Symphony X
Vision Divine
Judas Priest - I actually love the TURBO album.
Running Wild - On the few songs they use it, it is to accentuate the melody.
Axel Rudi Pell
Dio
Faith No More
Savatage
Type o Negative
Virgin Steele


and the best?

SABATON!

Nice list. I would also add Nightwish..
