So basically TIFF is good for preserving the quality of images but not space while with JPEG it's the opposite?

So you don't know that for sure? Because if that is true then that means that PNG is much better for sigs than JPEG. Personally, I haven't noticed anything too noticable when changing a sig image from a PNG to JPEG file or when I save a JPEG sig image repeatedly.
