% health runes are mid game, in between flat health and scaling health.

scaling runes usually beat flat runes at level 6-9

% health depends on the champion, but it can be between 1-6 when it beats flat and scaling, but then gets beaten by scaling unless, like you said, you're at 5k health.

Garen, Vlad, Sion, Mundo and a few other champs tend to be better with % than scaling as it helps with their mid game power, as late game they have so much health, all health runes are wasted regardless of whether they are flat, scaling or percentage, and their laning phases are either so good they don't need runes for help, or so bad they can't be saved by runes.

and after all that, it's still preference.
