Yanks often used to notice 50Hz flicker. Now that most sets are LCD which inherently has no flicker the field rate isn't so important.
At the Broadcast Engineering Museum we have a demo with three unlabelled monitors side by side. PAL, SECAM and NTSC. All fed with the same digital component source via high quality standards converters. We ask people which is which. For those who know, NTSC is easy. Just look at them in peripheral vision and the one that doesn't flicker so much is NTSC. PAL and SECAM can be remarkably hard to tell apart. With test card F displayed you can see the missing high frequency gratings in SECAM as compared to some cross colour in PAL.
