Definitely Broadway.
Concerts, I only go see Springsteen now, he's the only one worth the hassle and the money.
The horror that is the Meadowlands with the building of the new Giants Stadium and the Xanadu project makes going there for concerts a huge hassle. Usually it takes ages to get out of the traffic jammed parking lot. If you're very unlucky with parking you have to shuttle bus over to the stadium..it's just not worth it.
Sports-I like some, it's just pricy and I like the comforts of home. Football you freeze, baseball you bake out in the sun and there's public bathrooms and no pause like on my TV.. LOL But if I get free tickets I'm there.
Broadway: easy peasy to get too, especially on a Sunday when the city is quieter and there's no traffic. I can get from my house to the theater in about 20/25 minutes on a Sunday afternoon.
Park in a garage steps away from the theater, go in see the show(and I LOVE musicals!), be back home in a half hour.
