I just recently tried out the Oriental paper. I've been a loyal Ilford user for a while, but the student price on Oriental from B&H was too good not to at least try it. I'm very impressed so far. The contrast is different, but I split-grade print so after a bit of adjustment, I seem to be able to do everything that I could with the Ilford paper. I think the paper itself may actually be a bit heavier than Ilford.
If the prices were the same, I'd probably stick with Ilford, although more out of loyalty than any significant difference in quality. As it is, I'm switching to Oriental for as long as the price hold up.
