If the engine hasn't been abused and they're in spec, there's no reason not to reuse rings.
Given an In spec ring that performed for many hours flawlessly, vs a made in china untested new ring ,
I'de reuse the old one..
In theory, If the engine has overheated in the past, the rings may be low on ring to cylinder wall pressure and cause low compression and allow an excessive amount of oil to get by.
I've heard others say rings loose tension after running a few hundred hours even if not abused,
then blowby causes build up of deposits which causes rings ri stick on piston.
My experience has been: on engines with the rings stuck on the piston due cooked oil caused by piston high temps, ( I've only seen this on engines that have been run way too hot for too long.) after freeing up the rings and breaking the glaze on the cylinders they've all ran fine afterwards.
( sometimes gotta deal with one or more of: piston so loose in the cylinder it rattles around, scored cylinder/piston/rings, oval shaped valve seats due to worn valve guides, burned exhaust valves/seats )

Just break the glaze on the cylinder walls if the hash marks are gone and if there not too far gone they will reseat. Remember to keep the gaps staggered and don't put them back all lined up. To speed breakin when replacing I use chromium rings when they are available for the first rebuild if the cylinder does not need to be rebored.
