Does a patched tube affect wheel balance if you have a racing bike that you use for commute?
Does putting nylon liners between tube and rubber affect ride, speed, or efficiency?
Both:
Patch Kit Pros: Lightweight, inexpensive, works most of the time, and can fix more than one tire.
Patch Kit Cons: Won't fix every flat, takes more time, and adds extra steps to the flat fixing process.
Spare Tube Pros: Usually provides a more sure-fire fix that is easier and faster to perform.
Spare Tube Cons: Cumbersome and heavier than a patch kit, and alone, can only fix one flat tire.
So, I keep a tube (2 on my road bike) with me AND a patch kit. I replace the tube with one I keep with me, then when I get to work or home, I patch the punctured tire, and keep it with me to use as my spare next time.
