First: I think it's a fine use of DB bandwidth because it's good feedback and responces might be useful as long as they're not too flamey.
Right now I'd almost say B3d cause it seems more stable and less buggy and still faster as far as I can tell.
I don't like the way B3d handles types... what's up with the backslash? eeew. but that's just kind of a preference.
I think DB Pro is more intuitive and easier, but that's maybe just cause I'm used to it. If they fix db pros speed problems and bugs once and for all so it works as stable as db1 then for me there's no contest.. like in Berzerker one of the problems is it crashes to windows, but thats a dbpro thing... It's not like theres an error popping up in my code. If I wrote it in db1 it wouldn't do that. But what a pain without being able to use types and set globals.
I guess the decision if you gotta make one depends on how fast the db team can get it ironed out.
