Theoretically, a JPEG degrades every time it is opened, modified, and saved. I tried over 100 edits to a photo, and the last one looked as good as the first, so I'm not concerned about degradation.
As for JEPG over TIFF, in my case, it's just habit. JPEGs are much smaller than TIFFs, and I have the raw files if I need them.
