Hi James,
I can comment on both the boards your asking about.
The 9'2 Psh AA - Very nice looking fun small board with a rounded nose but very thin swallow tail. Like most PSH sup's you only have to take 1 look at the tails on them and you can see they surf well.
Nice quality board and the one we had in the shop went super quik! So got more coming.
The Oxbow 10ft - Pretty different board to the PSH, not as higher in performance ride but still pretty fun.
If i had to choose either, i would go with the 9'2. Shape wise, performance & quality.
Also to Billboard's comment, it is impossible for a shop to have a demo board in everything. If we did, we'd have like 50 -60 board in a demo fleet, that's silly. Demo boards are picked by trying to find what going to be most popular.
Hope that helps you out a bit James.
