Thanks for the comparison. I currently use Ilford MG Classic and was thinking about trying some Adox MCC. But the Adox paper is more expensive than the Ilford paper and, given your results, now I'm not sure it's worth it.
Edit: I haven't been Selenium toning my prints (I keep hearing how nasty the stuff is) but it would be interesting to see before and after photos of your prints on MG Classic. Wondering how much of a visible difference the increased DMAX makes.
