I'm comparing those papers too these days, finally got Fine Art Pearl today. And I'm also comparing with my current favorite; Ilford Smooth Pearl. I use an epson 4800. So although it's not answers to your questions, please allow me to post some of my first thoughts:
The Hahnemuhle prints became really blue yes, when using the profile from their website. (then again the error could be mine I fear). However it came out nicely when letting Printer determine colors.
For my own images deep deep blacks is important. Matte is not a good option for me from what I've seen so far, even though the reflections in coated papers is troublesome with the sizes I print when framed (around A2). If anyone could point out other papers that I might like it would be very helpful.
The blacks of Hahnemühle were the poorest. Those prints looks grey compared to the others. The coating of the Hahnemühle was the least dramatic, BUT it was much more prone to give a sheen at different lightning angles, thereby rendering it even "greyer". The Innova paper seems to have slightly darker blacks than Ilford from what my eye can see. Apart from the texture, thickness etc. these two papers print very similarly.
I think I will be making a choice between Ilford and Innova. I'm starting to really like the Innova surface, but based on another thread here I don't know which batch-version of Innova I've got, and what I could expect to get in the future.
EDIT: Has anyone got an idea what differences in longevity there might be between these three papers with the new epson inks? That would of course make a big impact on my choice. I can't find any information on this, as with almost all papers. Wilhelm Imaging only tests some, for me, uninteresting papers.
