I'd recommend King, except they wouldn't OEM me because I'm 'one of the little' guys. So King sucks mailorder wangers, who woulda guessed.
Anyway, I guess I'd get a King mailorder anyway, coz they're only a hundred bucks and once you put them on, you can pretty much forget about them, for, like, forever.
What do I run on all my bikes? An obscure headset called the Tange TechnoGlide that I have to order from Japan coz that's the only place I've seen them sold.
On customers bikes I've been spec'ing FSA Orbit X, which seams okay. Seals aren't super, but we'll see how they go.
