Taken from the article on the party boy/girl perk over at the wiki:
Notes
With the doubling effect from rank 2, several alcoholic drinks become competitive with chems in their effect, except alcohol is ostensibly cheaper to come by and addiction immunity comes built-in to this perk.
vodka and bourbon become potent health boosters; potentially very useful on survival where the instant effect of bonus health or bonus endurance is preferable to the slow regeneration of healing.
wine and various ice cold gwinnett beers (ale, brew, lager, pale, pilsner, stout) provide significant AP bonuses.
Beer and various Gwinnett drinks can be more effectively used for bartering benefits and speech checks.
And the melee damage boost of all alcoholic drinks (especially whiskey) becomes more significant.
The rank 3 effect does not show up as part of the item's PIP-Boy description, but it can be verified by either looking at your SPECIAL stats after consuming some alcohol or looking at your active effects.
The second rank doubles the negative effects of alcohol along with its positive ones. (+2 strength, +2 charisma, -2 intelligence)
So booze combined with the party boy/girl perk line plus buffout and maybe other chems I can't think of right now
