From what I know, Bromazepam is more anxiolytic, and is good for managing anxiety during daytime, while Temazepam is more sedative and better for sleep. Both of them are quite euphoric. I have tried Temazepam, it was very sedative and was far better than Diazepam, very short lived though. I can't speak for Bromazepam, since I never tried it.
