I think Seagate had a bad run for a while, but things seem to have improved. Hard to say, I know folks who swear by WD's and others that swear at them... I've always liked Hitachi drives.
Update on the 1TB WD Green drives: I am currently copying all the files from one of these drives to a new one, one internal and the second connected via eSATA to an external box. First off, the sustained read/write transfer rates are hovering around 60 MB/s, which isn't too shabby. However, the really interesting thing is the entire process is dead silent --- no noises whatsoever. Lastly, the external non-cooled box is maybe three or four degrees warmer than room temp, and fans running on slow in the MacPro.
