I recently did come comparisons of Adox, Oriental and Arista Ultra VC fiber papers. I found all three very good papers and on par with Ilford. If I rated them on tonality and coldness with my processing methods I would place Oriental and and Adox first and Arista a close second. Adox is slightly faster and responds to toning (bleach/sepia/selenium) better than the other two.
The Oriental I used was purchased late last year and I have read a couple threads that say the emulsion has changed again so I will have to buy a 25 sheet pack and try it again.
