Any resolution that's of multiples of 4, should come out clear on an LCD monitor. The reason they don't come out clear is because LCD's have built individual lights for each pixel on it's native resolution. If you make it less then it's native resolution, it tries to use a fraction of a pixel to light up a whole pixel which blurs it out since it can't do that. If you upscale beyond native, it wont be able to display all the pixels.
So on a monitor with 1440x900 native, 360x225 is really the highest low you'll get a crystal clear picture with. Any resolution on an LCD though will get you a more clear picture than an old CRT though, and like AndyUK said, this might have been the intent. However because I already know and appreciate what pixel art looks like off of a blurry CRT, I'd prefer seeing it as clear as possible - on an LCD
I disagree with your idea that CRT's are automatically worse. It's just that making CRTs of very large sizes is very impractical. That's the reason why LCDs are taking over.
For a vintage video game system a CRT TV is better. You get an analog signal from the console which directly drives the CRT in the TV. On an LCD TV the analog signal has to be digitized and upscaled to the native resolution of the screen. While theoretically pixel art could be nicely scaled at multiples of the original resolution by duplicating pixels, the LCD will most likely scale it as a "photograph" (some form of bicubic resizing probably) since movies and TV shows will look better that way.
Also, many systems used non-square pixels, for example the NES, SNES, Sega Master System, Colecovision and Sinclair Spectrum all used 256 pixel wide screens. If you want to display those at their proper aspect ratios you have to resize the picture.

Oh don't get me wrong, I'm not directly disagreeing with you. I will play an older game on a CRT without complaint, I'm just voicing an opinion here.
However, in response to the upscale, you're right with regards to TV's which might have all this scaling stuff automatic, however if we're talking about using a computer LCD monitor (remember, if you own a console and the game, it's legal to possess the roms), then depending on your video card settings, you'll likely have a better picture on the LCD monitor. I speak from personal experience though. I've found that my LCD monitor has a generally richer amount of color and clearer picture when I sat it side by side with almost any CRT TV I've used. Maybe I'm lucky, idk.
If we're talking about reliving our past, I will gladly grab an old CRT monitor, pop in an old Genesis with Sonic 3 and Knuckles and enjoy myself.
