To be fair, when you switch from one map editor to the other, you lose quite a lot in both instances. How much you lose is debatable, mind you.
I'm personally waiting for Oogaland's SRB2 Builder, which supposedly incorporates many of WadAuthor's good aspects with the solid interface of Doom Builder, adding many original features of its own. It's still going to take a while, though, I'm afraid.
