I patch. And it's always a good idea to use the "right tool" for the job. Rema patch kits have a well earned reputation. As others have mentioned, it's a good idea to carry a spare tube as well as a patch kit. Quicker and easier to replace the tube and then patch at home. Another good idea, and one I've seen some skip, is to run a piece of cloth, or drier sheet (anything that will snag), around the inside of the tire, so as to ensure whatever caused the flat is no longer there. You could use fingers, if you don't mind a bloody finger.
