Curious - what other alcohols?
The downsides tend to be foul taste and massive potency - much over 15ml can kill someone. It doesn't undergo metabolism to aldehyde so the traditional hangover doesn't happen, and the duration can be much longer.
There are others. I'm not vouching for the safety of any of them (even ethanol!), for the record, and have not tried 2M2B.
I did read something about a guy who had used it to make 'vodka', by adding a few ml to enough water that a shot would have a similar effect to ethanol-based spirits. At the concentration the report said there was a sort of minty-chemical. I would imagine further dilutions with a mixer would hide that.
