I really like the Borgata. I don't typically play enough there to earn the black label, but I keep my Harrah's Diamond one current and Borgata matches it every year.

The good--

1) I'm primarily a $50 BJ player with some slots, mostly $1 but also some $5. Comps are very generous. Table comps are MUCH higher than Harrahs properties even with the frequent multipliers at AC Harrahs' properties.
2) I rarely have trouble getting a room.
3) Spa is nice
4) Best concerts in AC
5) Good restaurants...can't beat Bobby Flay Steak!

The Bad--

1) Restaurants are very expensive.
2) Black Label Club almost always has a line and charges $10 in comps.
3) Check-in lines are LONG
4) Tables are very crowded...
