I "finished" BotW and then spent probably another 150-200 hours on it after. It didn't feel like it was really done until I found all of the shrines and armor sets. I never finished TotK because the sky was annoying to navigate and the underneath area was very samey. Also I found the new mechanics to be a little too immersion breaking. Not that BotW was the most immersive game ever. I was really disappointed with TotK.
