I'll take a harder look at Dojo but back when I made my choice, Extjs
had a better looking and more complete widget set.  (And beauty is in
the eye of the beholder.)   Here are some head-to-head comparisons
from 2 years and 1 year ago, respectively:



But that was then.  All js frameworks are progressing.  You can view
the current offerings:

Dojo demos are at http://demos.dojotoolkit.org/demos/

Extjs demos are at http://extjs.com/deploy/dev/examples/samples.html

Dojo has a big advantage -- they're open source for commercial use
unlike Extjs.  I'm a single developer so I didn't find Extjs licensing
a burden.  For many, this is a deal breaker.

I also have issues with code generators and like aspects of
Javascript, particularly vs. Java.  To play devil's advocate, though,
code generators can decrease the amount of code necessary for a
particular UI.  It will only include the exact parts of the necessary
framework (unlike a more blocky library include) and can also build
browser-specific code, which is probably tighter.  I don't know what
the true savings might be when you consider caching and Google AJAX
Library API.

Also, not everyone is as good a coder as Alex so at least in my case,
generated javascript is as good or better execution-wise if not
