I'd say that it's as good, but it's different. It's much smaller inside, and they offer different items. While they both do indeed do desserts, Boardwalk seems to focus a bit more on cakes and cupcakes than pastries, and they have a standard sandwich menu available throughout the day.
On our latest trip, I got a chocolate eclair from there, and it was awesome. Then again, it's kind of hard to screw up an eclair, so long as you get the custard filling right. And they did get it right. And it was delicious.
