Default [Q] overall slowing of OS responsiveness over time

Has anyone else noticed that their Moto X doesn't seem as "snappy" as it used to? It feels like I'm waiting a lot longer for the camera to open and take a picture, it takes several seconds to attach a photo to a message using Hangouts, SwiftKey doesn't pop up as quickly, etc. I've been running 4.4 since AT&T pushed it out. I'm considering doing a factory data reset to see if it helps speed things up, but that's a bit of a hassle so I've been holding off. Just wondering if anyone else has noticed this.
