What’s the point of expensive liquor? Does it make you more drunk ? Increase the time of drunkness?

So I walked into Costco and saw cheap generic vodka and i saw the name brand goose which was 2x more expensive.

I’ve experimented with my body and it takes about 3 shots of vodka to get me drunk. If I take 3 shots of the generic vodka vs 3 shots of goose , will there be a difference?

I mean I don’t understand, is it the taste ? What’s causing the gap in price . Will I be more drunk or get drunk longer with goose because it’s more expensive?
