I must say Gaara vs Rock Lee was a very good fight scene.
Alucard vs anyone is pretty awesome, can't wait for the OVAs to catch up to the Manga.
Also Tenga Toppa Gurren-Lagann vs whatever the anti-spiral thing was called, possibly the single most epic fight.
Kira vs Le Creuset in SEED was good aswell.
I also have a vague recollection of Bleach having some pretty good fight scenes in but can't recall a particular one.
