Er, isn't blackjack usually against the house? I always thought of poker as the quintessential "fun with friends" game. Hang out, drink a couple beers, everyone pitches in $10 on the poker game to make it entertaining.
friendzis is contemplating playing with friends at a blackjack table at a casino (which can be super fun, second to a hot craps table, IMO), not playing in a home blackjack game (which is dreadfully boring).
Blackjack isn't really a party game.
