AC casinos
First, bear in mind all AC games are 6 and 8 decks.
However, the rules are quite liberal. Under typical AC rules, playing perfect basic strategy including all the "fine points," the house edge in the 6-deck game is about 0.293%.
Typical (if not universal) Atlantic City rules are: 6 decks; DA2, SAP(3), S17, resplit and rehit split Aces, NS, plus a 2-card 21 resulting from a split is considered a fresh hand, and thus is paid 3:2 as a "natural."
Caesar's Boardwalk used to be my favorite, but that was before Caesar's was taken over by PPE; so I don't know if the atmosphere/games have changed since then.
The two Trump boardwalk properties, and the Showboat are other places where I have done well. Stay away from the Sands, the Claridge, and the bayside properties. The rest (Hilton, Trop, Bally's Park Place-Wild West and Resorts) are "O.K.," but not as good (IMHO) as Caesar's, Trump Plaza, Trump Taj Mahal and the Showboat.
