Honestly if you have older hardware, like a couple years old most of the most popular distros are pretty stable.
Ubuntu on hardware a few years old will chug along without issues more often than not especially if you are just using it as a glorified thin client for Chrome which is an increasingly large base of users.
There are of course some gotchas with things like integrated graphics and dedicated graphics in laptops or some device drivers for peripherals like printers (it is still linux after all, year of the linux desktop any year now aha)
