The choice between SproutCore and Cappuccino is largely philosophical (port something that works, or build fresh with new perspective), and based on limited data. The way I see it, either choice is still a choice for a client side web framework, and that's a step in the right direction. For instance, Narwhal/CommonJS/SeedJS came out of these efforts, and benefit all involved.
