For IDE I have used 'em all... Fujitsu, IBM ('Deathstar'), Maxtor, Seagate, WD. For my money, I'd go WD or Seagate... but I'm sure everybody has had both positive and negative experiences with all the brands.
In some of the forums I visit, I have come across references to Maxtor drives being more sensitive to overclocked bus speed-related issues. Personally, I have not had this problem, but you may want to keep that in mind if you overclock using a mobo that doesn't lock the PCI bus speed to 33mHz.
From my IBM experience, I'd suggest staying away from drives which employ large advances in technology, or the very newest in technology. Wait a few months... let somebody else be the beta tester
The IBM 75GXPs, for example, were IBM's first release of a platter surface technology that had significanly increased areal density compared to the 60GXPs... and a relatively high percentage of these 75GXP drives failed prematurely (I owned 4 of them).
