Advantages of Synapse over other data-binding libraries?

[kokujin]

Can you list other advantages apart from file size and no use of extra code in HTML templates? Are there any benchmarks?

It is designed to be pluggable. I created it to learn more about approaches to data binding and to understand the overlap between event systems. I do not have benchmarks and won't until slowness is observed. It's not doing any magic and relies heavily on existing event systems, e.g. Backbone, jQuery.
