I mainly have experience with Diazepam and Alprazolam (others too but not enough to make a proper assessment). I find Diazepam to be the perfect “functional” benzo. Yes it may be sedating, but in reasonable doses it’s not going to knock you out. It has a long duration, subtle but very relaxing effects. I practically never black out off it, even in higher doses (alprazolam makes me black out pretty easily if I take even a moderate dose). Alprazolam also gives me more of that “don’t give a fuck” feeling, so makes me more likely to say / do things I otherwise wouldn’t (some people may like this), whereas diazepam just makes me feel chill. Alprazolam also affects my mental faculties far more than diazepam. As I like to say; alprazolam goes to my head, diazepam goes to my body. From my limited experience, I could imagine clonazepam in moderate doses being fine too.
