DD gets my vote too...
The wow factor that hit me when I finally left the DD healers village only to discover the absolutely massive world before me and all the things, people and places to see is sadly lacking in BD.
I just don't like the split acts in BD. They all appear too small to me, like mini versions of DD's whole, but with far less substance. I don't care about any of the characters or people I meet as I know they'll be gone or dead when I leave the act and basically...start again. Find another base of operations, find npcs, find places of interest...finish act, rinse and repeat!
How many games other than DD can boast that even when you're 50 hours of play into the game you can return to the very spot you began the game by hopping into the teleporter, or running there if ya wanted! You could constantly open new areas, and go back to the same npcs from ages before to find out something new or get a new quest.
If I never played DD I'd probably be enjoying BD more, I am enjoying it, but there's a small empty place in my heart that only DD could fill... <img src="/ubbthreads/images/graemlins/puppyeyes.gif" alt="" />
