NTSC has a problem with flesh tones, or did the last generation of analogue sets here in the states no longer had those issues. What I hate about PAL is the 50HZ refresh rate, I cannot watch it for more than a few minutes a time without getting a blinding headache. I don't see how the rest of the civilized world could put up with that.
Same way you don't notice the 60hz flicker from lighting, or only notice the flicker at the movies for a few minutes, or none of us used to notice the awfully low resolution even of deinterlaced PAL, your brain adjusts. If you'd never encountered a TV, monitor, cinema, AC powered lighting etc you'd notice the flicker of 120hz sets just as bad as you did with 50hz and everywhere with any AC lighting would look like a rave to you. After a couple of weeks not been around anything with a refresh rate lower than 120hz street lighting and friends house lighting gives me headaches. Doesn't take too long to adjust and not notice it again though. At most a day.
I can remember deinterlaced PAL 60 been the "gold standard" for (non PC) gaming for a few years and it looked amazing. PAL colour and resolution with the only thing NTSC was better at thrown in. Looked much better on widescreen sets than either other option too. Unfortunately most TVs couldn't handle that until it was too late for SD content.
PAL resolution isn't really that bad--remember the extra horizontal resolution of Digital HD is spread over a larger relative distance with 16:9 compared to 4:3.
SD is about the same as PAL,in any case.
"Simple PAL" without the delay line could perhaps look to have poor vertical resolution.
It was never sold in Oz,& the Colour sets I saw in the UK all were the delay line type as well.
Line Structure is another thing ---with reasonable sized screens at a normal viewing distance it wasn't visible.
Only a generation of kids who grew up sitting about a metre away from the screen started to notice it.
In any case,the technology to artificially double the scan rate
was available,& made it much harder to discern line structure.
In the early days of analog TV,on air staff were well aware that wearing patterned clothing like "hounds-tooth checks" was a "no-no",as you got nasty strobing effects from interaction with line & field rate scanning----it was even worse with colour.
At some time this wisdom was lost,with some horrific results in the last few years of analog.
Digital has its own problems,like a presenter in a red dress standing in front of a red background.
She looks like she is growing out of the background.
