I've used both on apps that have been released to the various app stores. I've used jQuery for years so logically I thought jQuery Mobile would make the most sense. I used version 1.2 and it was just mediocre. It'll get the job done. There were definitely some hurdles. I liked being able to design my interface in HTML with CSS. My experience with Sencha was completely different. It was very hard getting started as I had to relearn the Sencha/ExtJS way. I began to like the way each page/panel is "described" as JSON in a JS file. It's a completely different way of skinning a cat. Things like stores/models/views/controllers are baked into the framework. Support was absolutely abysmal. I think there were a couple of guys on their dev forums that actually knew their stuff. Quite a few "it works fine for me" type answers. Things blatantly left out of the docs which may be fine for normal users, but was extremely painful for a newbie. In the end, I really liked the results from Sencha far more than anything I'd ever done in jQuery Mobile. I will say, my app in Sencha was extremely "templatey" which means it looked like a stock iPhone app... nothing custom at all.
