Dojo is particularly good at offering a transparent way to use
whatever resources are available for such things as local storage
(also similarly for graphics &c, I think, but I don't do much graphics
so I don't know for sure - also that doesn't matter to offline work;-)
-- whether it's some small browser-specific local store, HTML5, Gears,
whatever. (It can even fall back to the server as the last resort iff
no way at all is available locally -- all more or less transparently /
declaratively, without needing to contort your application level code
for the purpose).
Not sure if other frameworks have caught up to dojo on this
"transparency" issue by now, back when I researched this it was really
a killer feature for dojo from my POV;-).

I guess "best looking" is a subjective call and I don't claim
expertise on "looks" -- dojox.grid,
, seems fine to me;-).

I have my issues with code generation -- ORMs that generate SQL on my
behalf, GWT, Pyjamas, Visual Studio's long-standing GUI builders, etc.
They never make code as good as I'd write by hand, and they always add
limitations. And editing the generated code is a sure road to
I like GUI builders (since I'm no good at graphic design anyway, the
looks they generate won't be worse than the ones I'd make by hand;-),
but I'd rather have them generate _data_ -- and then a simple engine
can paint the GUI based on the data -- the approach XCode and Qt
Builder take, on the desktop. I don't know if anything like that is in
the offing for any JS GUI/toolkit framework, though.
