I like going to see games in Walsh. Small courts like that have their own charm. It reminds me of the era where teams all had their own small little band boxes.
That said, it has become increasingly more difficult to get tickets. The Prudential center is nice, but definitely a different experience. FYI, if the games ever do get moved to the Rock, building the time to go and eat in Newark Ironbound section. It's a short, reasonably safe, walk from the arena and the food is amazing, albeit a little bit pricey, depending on which place you go to.
