I know Charlotte Rae's background goes back further, but I believe she was much funnier here than Diff'rent Strokes. In Diff'rent Strokes, her humor was generally either dark, bland, or in poor taste. In FOL, I just get a kick out of her jokes. It sounded much fresher and more funnier than her stint as a supporting character. But that's just me.

She was funnier, because she had more jokes written especially for her, considering she was the star of FOL.

Well she was the "star" of season 1, but more supporting after that IMO.

She was funny on both.
