Always normal. Like Assassinator said I'm in it just for enjoyment. Only cases where I'd choose Hard difficulty is if I were to play the game again and wanted a challenge since I have already cleared it regularly and doing so again would be boring. Example: Nuzlocke runs on Pokemon games.


Also I'm not the best gamer when it comes to most genres of games, I tend to miss stuff or something similar so usually normal difficulty is challenging enough.
