Yeah, I can agree on this. If you're running subnative content then a CRT is absolutely the way to go.
But I'm using a good upscaler, so I don't have that issue, fortunately.
Well, admittedly when I'm saying this, I'm mostly thinking in terms of PC gaming. I'd been using nothing but LCD monitors for years, until I picked up a nice KDS CRT offa eBay (and picked it up in-person, which was a unique experience - rather liked the conversation the seller and I had before putting the big, heavy box in my car) for use with a Windows 98 machine (for authenticity, I guess). Started playing some old games with it, and thought they looked drastically sharper than what I was used to for games that old and low-res. Double-checked the resolution they were running at, and was surprised to see that was lowly 640x480. That'd have looked like a bilinear-filtered mess on my modern widescreen monitors (and potentially wrong-aspect-ratio to boot, though that's usually only a few menu options away from being fixed - though I also recall having to set that
every single time for some of my monitors, which got tiresome).
On the other hand, that CRT also supports 1600x1200, but even going as high as 1024x768 shows a bit of a distorted effect - like there's a subtle bright line wobbling all over the left side of the screen, which gets worse the higher the resolution gets. So, for high-resolution stuff, I'd probably prefer a good LCD monitor (I mean, shit, I went out of my way for an XB271HU to try IPS out, and I'm pretty pleased with it for modern gaming).
As far as upscalers go, I did like the XRGB-Mini well enough... though I switched away from it to CRT gaming (for now) because the signal loss on power-on/resolution change was a deal-breaker for me. Really wish something could be done about that, it was so good otherwise...
