Not a big fan. On pretty much every game where stealth is possible (MGS, Assassin's Creed, Skyrim/Fallout, Deus Ex) I will sneak as much as I can until I am very easily discovered and proceed to shower the guards or whoever with violent and brutal deaths. And then I realise "wait this was a lot more smurfing fun than crawling around on the floor for three hours, why didn't I do this sooner?" and that's the end of that.
