While chains do not stretch over time like belts do, they do wear over time, which has a very similar effect. For the most part in my experience neither phenomenon is typically noticeable in a robot during a standard (1-2) event season, but both can be observed on a practice robot with sufficient hours of use. In a high-use demobot, both have a potential to give you issues if you use it long enough.
Both chain in tube and belt in tube have been done successfully in competition-- 1625's Lobster Drive and of course 118's chain in tube come to mind as examples of belt and chain respectively.
