Raw pixels for me. I think it may be because the only 2D games I grew up with were on handhelds like the GBA SP and the DS, so I never saw 2D sprites on a CRT. Recently, though, I’ve been experimenting with CRT shaders for emulation. They’re visually amazing, but I haven’t found one that’s perfect for my tastes (especially for 3D games with upscaled resolution). Perhaps I’ll give it another try when I replace my old HD TV with a 4K one.
In the end, everyone can enjoy gaming however they like, but I’m a bit skeptical about the “look intended by the devs” argument. Sure, CRTs were the only displays available for those consoles at the time, but given the huge variety of TV models, signals, and regional standards, it’s nearly impossible to recreate a single “intended effect” for all of them (For ex, with the SOTN eyes effect, many CRT shader presets I tested didn’t reproduce it accurately, though perhaps that's only on a real CRT). And not even mentioning PC or handheld ports of the same games, which ran on completely different displays.
As another user said, for me playing a game with raw pixels is like watching a remastered version of an old movie: the details are sharper, but you also risk seeing details that were once hidden (like traveling rails or camera reflections). Still, I don’t think that makes it an illegitimate way to enjoy retro gaming, just a different approach.
Maybe I’m all wrong about this, I’m far from a CRT expert. But I’d love to read/listen to developer interviews on the topic.
