In 2011, the scaler chips in LCD TVs mentioned became decent and standardized. Before that, results varied. You could get a blurry picture even on RGB Scart, you could get a sharp picture with doubled lines, or if the LCD resolution was lower than 800x600 (such as on smaller 4:3 TVs), you could get a sharp picture, but it would squash 320x256 to 4:3 and skip 16 scanlines - every nth line. It was just a bunch of different chips that did things differently.

Not all versions of Deluxe Paint will draw a perfect square. Usually the tool will draw a Xpx by Xpx image, but if your screen is squished because it's NTSC, when it gets stretched, they will look tall.
I realized this while testing this same issue for a very troll-friendly thread here : http://eab.abime.net/showthread.php?t=82793

That chapter is for setting up 1:1 pixel aspect ratio on CRT displays. The article says to use the Grid or Coords tool to ensure that it's really square - in pixels - before whipping out the ruler.
I do go through graphics drawn on NTSC displays, and certainly all graphics drawn for PAL or square pixels will look stretched on NTSC - graphics drawn for square pixels slightly less so. Whether to draw specifically for NTSC CRT displays today is really up to the artist, but as I mention in the summary Amiga users will find a way
It's all a matter of practicality, and today it just has to be square pixels I think. I've had to abandon my fierce conviction that they should be PAL pixels on CRT only; I simply don't have as many arguments against square pixels as I have for PAL-squashed pillow-shaped ones.
