strip blackjack is ok but make sure you have the following rules:
6 decks
blackjack pays 3:2
dealer stands on soft 17
split up to 3 times (including aces)
double after splitting allowed
late surrender option
that brings the house advantage down to about 0.25%.
you should be able to get more specific info on both games over at
