I use and really like Ilford FB Matt.
YES you will get the full range of tones but because the paper has a Matt surface you will not get the full black that you get with Pearl or Gloss. But when I say that, the paper gives the fullest black that it can but because it has a non reflective surface it will have more like, what I call, a 'charcoal black' look to it. Especially when wet and when dried and not laid out next to anything else it will look as good as any print, but if you compare a black on Pearl or Gloss next to a Matt print, you will see a difference.
But what it is really about is, do YOU like the look of the finished print.
I would highly recommend that you give it a go, maybe trying with a small sized box full or maybe someone closer to you would be willing to give or mail you a sheet or two to try, for the cost of postage and paper? This is something that I have done with others in the UK to try paper that I have and that they were curious about.
It is also said that if prints of different surfaces, including Matt, were framed behind glass, one would not be able to tell the difference.
If only there was a way to show what I meant on screen, but there isn't...
