Nobody uses scanline filters because they are nostalgic about it.

It just LOOKS better that way. It's a nice compromise between jaggy, unfiltered graphics and blurry filtered graphics.

That said, I USED to think scanlines were retarded. I didn't know anyone actually used them, I just thought to myself "Oh wow, what a useless filter." But after tinkering with several filters over the years (From unfiltered 16:9, to hq4x, to bilinear), I've found that the one that's most pleasing to the eye is a scanline filter, even one that's just a bunch of dimmed bars showing on the screen.
Pic related is almost ideal, though I could do away with the curved screen.

Granted, it's not as good as playing on a CRT, but it's a hell of a lot better than unfiltered.
