I'd say benzos because pregabalin can turn me into a complete lunatic. Everyone is different and just be careful to not end up with a habit. Pregabalin is more recreational IMO, whereas benzos serve quite a specific function. Gabapentin I can't remember too well but it might be a middle ground - it didn't have that same mind-fuck that pregabs can have. in fact, I think it might the better of the three on reflection but this is based on limited experience. Where I've lived, pregabalin has been a street drug and benzos are always around of course, but gabapentin didn't seem to affect me too much. But I can't speak too much on that due to only using it a couple of times. Between benzos and pregabs I'd say benzos but please be careful of addiction.
