What kind of phone is it? if it's a Nokia then it depends...
If you are okay with rolling back to 8.0 once the official 8.1 comes out, then I would definitely get DP8.1. Just to let you know, rolling back to 8.0 will erase all of your phone's data--it can be backed up in the settings. You can roll back with this if the phone is a Nokia: FAQ - How can I recover/reset/restore my phone software? - Nokia - USA
If you don't want to go through all that trouble of rolling back then I would just wait.
What I would do: I can't see myself with 8.0 because in my opinion, 8.1 is light years better. I would go for the DP8.1 and just roll back when the official 8.1 is out--OR wait for the fix that Microsoft is working on.
