In the 70's and 80's we always dreamed of having sharper and just plain'ol better video out from our consoles & computers. But we rarely spent effort to achieve that. VGA and S-Video and Composite displays/televisions were available then but not so much the modifications and converters to complete the interface. Not even the simple 1-transistor VCS composite converter. We were happy with RF. And that's what the games were designed for.
Mods as we know them today came about from the necessity to move toward modern displays - which increasingly lack the classic inputs. And it was this slow evolution throughout the 2010s that drove the popularity of mods.
The necessity to play and not the improved image quality is what's behind everything ranging from the 1-transistor mod through the FrameMeister through the latest open-source converter.

For those of you wanting consistent sub-millimeter pixel-perfect accuracy worthy of microscopic examination, there's nothing better than a software emulator running on an HDMI display. Without filters You can see your game in all its blocky ugliness. And more. We wanted that back in the day. Not so much today.
At the other end of the spectrum most emulators today allow for tuning and flavouring of their outputs. Replicating subtle 20% scanlines, NTSC fringing and artifacting, blurring and blooming, distortion filters, CRT-masking, achieving beautiful color saturation and contrast.. All in a day's work for the best emulators. Not to mention the upcoming HDR option already in some emulators. Not to blow your eyes out with mega-saturation or brightness, but to give the best possible contrast & saturation across a consoles entire palette and final CRT output.
And it is this way (through a GPU outputting to VGA or HDMI) that I found the perfect display. Adjustable to look like vintage RF or any standard thereafter.
So for most things NES/SNES and earlier I prefer RF. Or the RF look through emulation.
