Default Best MinFree Settings for every day usage

So i heard that proper Min Free settings can make phones fly. So i wanted ask you guys the best suitable Min Free settings for everyday use. I mean, i use only 2 apps running in the Recent Task Manager so i don't think I'd set the min free such that its for multitasking. I play a few games though
