Yeah, you’re gonna need to be a little more specific.
As far as what the “best” are, that’s always gonna be dependent on the individual doing them. You’ll probably get a lot of common responses (most people will say BB back squat for quads, and RDL for hammies), but each individual will actually respond best to different exercises.
Tom Platz got ginormous quads from doing BB back squats, Dorian Yates said that he didn’t get much out of BB back squats and instead preferred to leg press.
Then you have things to consider like saftey, past injuries, equipment available, form, experience, etc…
