Grey Goose is filtered a lot more. That used to be my only drink when i went out to parties. No hangover the next day, even after blacking out. Much smoother.
If you're getting black out drunk maybe opt for something a little nicer but if you're just trying to feel good go for the cheap stuff.
I work as a bartender though and i can tell you that we have had the same bottle of goose up on the top shelf forever. Some people just dont feel like paying at a time like this. We're not a high end expensive bar either.
Are you looking for flavored or just some regular vodka?
