I like OpenLayers. We built a rather complex image annotation tool around it and OpenLayers worked well with all the features we added over the years, recently even a full-blown video annotation tool. The community is nice and active, too. Best of all: It's still compatible with our old school way of JS development. The only thing I'm missing is the API documentation of older versions which they seem to have dropped at some point.
