Specifically, what are you wanting them for?
My college's arboretum had a few spots that had them in it. This is what I can tell you from those observations, as well as others I've talked to (which includes a local native plant dealer).
As far as a good habitat plant yes... but not for soft mast. I haven't put them in yet on my property, but I've seen them growing in the area. I'm planning on using them to help replace A/O. I've heard basically everything that has been said above. Adaptable, not super high for browse, create structure, but not insanely thick, provide berries for wildlife, and great for pollinators. At the arb, they grew in some moderate shade, and on sandy soil. I never saw them in the driest areas, nor in the wettest, but it was not really a surprise to see them in between the extremes. I saw a little bit of evidence of browse, but not intense like one would see on elderberries. All of these are +'s in my book for overall habitat quality.
