I don't have any personal knowledge of the On-One, though I've read good things about them online. That company seems to produce pretty well-sorted stuff.
The White Brothers is exactly the same as one branded "Black Ops" or something along those lines, the only difference being $ and decals. The off-brand can be commonly found on Flea-bay for a lot less. 42mm rake, I believe.
The Bontrager carbon is well-made. It has 38mm rake, same as a Reba.
Pace was bought by DT Swiss early this year. Production on their forks stopped, and they are still backordered. Commanding lots of money on ebay. 42mm rake and magnesium crown/dropouts. Build quality notably better than the White. This is what I have on my bike, btw.
