Hi,
I think that each framework has pluses and minuses. I'm author of total.js and I'd decided for total.js because it's simple, extensible and without unnecessary dependencies. If you choose a good business logic then your project will work in each framework.
Express.js has a good community, was first and Kraken.js creates PayPal. This is a good premise for the start.
Frameworks have a similar performance. Choose what you satisfy more :-)
Thanks.
