I am flabbergasted that this guy gives the Ext documentation a better grade than jQuery's. I have to use both at work, and I can always find what I need very quickly with jQuery, but with Ext I end up hunting, sometimes for hours. Honestly, for someone just getting into Ext development and not want to use one of the pre-fab RIA stuff, the documentation is among the crappiest I have ever seen, for all its volume.
