As someone who has lived in both, I find the New Haven has a similar charm to Worcester. Both places in my opinion have nice restaurants and some surprisingly pleasant bars. The big difference is that New Haven is a lot more walkable, the restaurants and other fun things to do are all pretty much in walking distance. However, New Haven definitely can feel more like a big college town at times, whereas Worcester has a bit more of an identity divided from it’s higher Ed. Bottom line, if you like Worcester, you will like New Haven. It also is lovely being so close to NYC.
