But I've heard the OEM pilot bearing is crap-and the NSK one came with my ACT clutch so I'm leaning toward that one but thought I would get some more opinions. Tried search and didn't see anything come up about NSK brand. Thanks!

Check which one has a better seal and use that one.

NSK is OEM for a lot of **** including Subaru...but then again so is Koyo.

Whichever one looks better I'd used. I do know that 3/4 cars I have now have the NSK bearings in them that cam from ACT and Exedy.
