I have actually been mind-boggled (in the best sense) by the detail and specificity some of these articles have. A lot of times, with situations like this, articles will attempt to merely describe, or will contain a single static screenshot, but things like that 'slider' to compare in a flash the different graphical settings really puts it into sharp relief. I think the only thing to do at this point, when I decide to start the game, is to DL the Steam version, playing the opening in both "Classic" and "Hi-Res" for comparison, and simultaneously DL an emulated version with fan-made cleanups, and see which one just feels the most powerful overall. I know a purist would just say "PC, Classic, no question", but I can't seem to shake the FEELING that the cleaning up of the artwork has a...potential I guess would be the word, to be something great.
That said, I've been playing a lot of SNES greats on my SNES-Classic, on a big HDTV, generally using the CRT filter to avoid the 'accidental jaggies'...and I haven't had any complaints whatsoever. And that's alternating from Persona 5 on my PS4 on the same TV. So, overthinker over here. Then again, shit like "Mega Man X" is a lot less plot-based and delicate than CT...le sigh...
