Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
I don't know that it's not about the hardware @ all. I think that buttons & well placed functionality is still important on the physical part. Nokia's done a pretty good job w/ the 5800. I like the media button & the lock toggle a lot. It's a little creaky though.
