jQuery is easier to work with too, if you know CSS jQuery is really easy to pickup and use.
And jQuery is building mobile elements that will make a mobile style look almost like an app.
I think, JQuery would be wonderfull for small projects. But YUI 3 have more modular desing and API references are greate, understandable. Has a standard!, you might say. YUI 3 OOP 's not compared to JQuery 's OOP.
Having used both, my vote goes straight to jQuery with its clean, concise syntax and useful functions. That said, I have not even looked at YUI 3 - so I'm not really comparing like-for-like.
