So much of this is overwhelmingly influenced by CRT displays. Hbomberguy’s Scanline episode applies here.

I always much prefer to play at the marine resolution of what I'm playing. Not only do i want to have the same experience as of i was using the console but upscaling can often cause some oddities. Especially with 3d games whereas polygons are sharp and any 2d elements are still pixelated. I think that mismatch looks way uglier than the whole screen being pixelated.
