I haven't used those 2 but I've used jQuery, Mootools (a bit), ExtJS and a clientco's own in-house library.
ExtJS isn't free for commercial use, which appeals to some clients. It uses a object oriented component based system that you can use to build reusable UI widgets. Apart from that it does the same stuff as most of the others.
I've found clients tend to accept that if you've used a few frameworks and can show you know what's going on behind the frameworks then you can usually pick up a new one pretty quickly.
