Gosh thats a hard one (and my chemistry is shabby) because etizolam has a thiophene ring and a triazole ring so it's not really a matter of taking the thiophene ring out and subbing in a benzene one and seeing what happens. It's because they react at the GABAa receptor you will find it has "similar" effects to diazepam or alprazolam. I'm not sure if I could compare this molecule objectively to the others because molecular chemistry baffles me...
I could only offer you subjective opinions 'cause I guess everyone responds differently to a stressful situation or even if it's just a Sunday night chill with a beer. For me the closest I can think of (not in terms of structure) is diazepam, in terms of sedation and muscle relaxation. In terms of etizolam's weird, mild sense of euphoria and its brief "uppiness" when you first eat it - I can't think of a thieno or benzo that does that. I guess alprazolam would be a close candidate but for me, all alprazolam did for me was make me sink into my armchair and then feel weirdly aggressive, so I have nothing to offer but subjectivity I'm afraid!
