Religiously.
Anything PS2 and back I want them, I was a lifelong console gamer and grew up in the eighties with CRT TVs. Old games smoothed out at a higher resolution look unnatural to me. They look even worse stretched to 16:9 with no filters at all! A sin against god, that one! I've always felt like that, as early as Sega Dreamcast when it got a bunch of Capcom PS1 games ported to it, I was appalled by PS1 games smoothed out. Still am, ew.
I did stop using mega Bezel though, it taking 15 seconds to load some games was silly. Shame because they are awesome. I tend to use shaders that mimic NTSC RF with Sega Saturn and anything before it because that's what we used growing up. We lived in a more rural area, still do really, and RF here looks about as good as composite anyway. (I've seen video of SNES via RF in a big city and yeah...
OOF!)
We used to have a two consoles RF daisy chained plugged into a VCR plugged into the TV to be as efficient as possible since we tended to have the TVs with few connections. If you have a bunch of actual hardware and a scaler like Retrotink 5x or 4k, not a bad idea to get a VCR. I had that setup with my Retrotink 5x before I was forced to sell the bulk of my physical retro stuff due to long term unemployment. (but never my VHS tapes)
Now with Cemu, RPCS3. Naomi arcade... yeah I just jack up the resolution. I went through a phase where I thought it was funny to use reshade to make modern games look retro, but it was a brief fascination.
I use one in Retroarch called CRT-Consumer. You can find a version in the Glslp group and in the Slang group.
I find the slang version looks like how I remember my consoles actually looking when I finally upgraded to SCART leads to everything in 1996.
Consumer and consumer NTSC are terrific all round for me, along with Guest NTSC. I really like the kind of screen curvature Consumer uses as well, it's much better than what a lot of the other shaders use. You can modify it's parameters pretty darn well to mimic playing a PS2 on a CRT in 2002 all the way to playing a NES/Genesis on a CRT in 1988. the file labeled presets on the main slang shaders page has some good stuff in it as well.
