Chain technically doesn't stretch, but it does wear, albeit slowly. For us, chain wear was far less of a problem than bearing blocks getting closer together due to hole clearances. Last year we ran on one tension of chain for the whole season without any problems. I would say chain is the easier of the two due to the sheer amount of forgiveness it has (and it's ability to replace 20 pitch gears, but that's for another time).
There also seems to be a rare recurring problem of belt picking up field tape, although I have no idea why.
That is weird lol, though you when chain get slack it has sideways play meaning if you run chain too close to a bolt or wheel, you'll run into some problems. Belt has not play, and it can take a hit and be fine, though it really just comes down to what works best for the individual
