I'm sure it's already been mentioned or noticed here by people, but benzos don't bind to GABA receptors, they act as potentiators that essentially pretty pry the GABA receptors further open, if that makes sense. The pharmacology of GABA drugs is super nuanced and still isn't fully understood. Alcohol is also, as mentioned earlier, an incredibly messy drug as far as how it binds.
The description of a Venn diagram, with GHB on one side, benzos on the other, and alcohol in the middle is very applicable imo. Benzos are more "neatly drunk", and GHB is more "sloppy drunk", in this allegory (is allegory the right term here? I just woke up, sorry.)
Benzos have distinctly intense amnesia and delusions of sobriety, alcohol is perhaps the most toxic though. Keep in mind too that both vary, Jamaican rum vs cider vs vodka are so different, as are the majority of benzos from one another. In the is USA right now (the only area I'm familiar with) you're likely to encounter Bromazolam, Etizolam, Bromonordiazepam, Phenazolam aka Clobromazolam, Alprazolam, Clonazepam, Lorazepam, Diazepam, and each one is very unique, if you have questions about any of them feel free to ask away.
