Personally, the reason I still jailbreak is to get rid of the ridiculous animations and to use a five column springboard and dock with smaller icons. If Apple would provide this in stock iOS, I'd be less tempted to jailbreak.
The thing I dislike about Siri is that voice dialing and music playback are not local functions. You have to be in a good signal area for the request to be sent to the servers and back. Ridiculous. I've turned Siri off and just use Voice Control.
