Doing a quick rolling shutter test it seams to be very little when set to 720p50 and 1/60 shutter. Not ideal for shooting in PAL country but very little rolling shutter. It's like night and day if you compare with other shutter speeds in 720p. Somehow the optical illusion masks the rolling shutter pretty well. Alot of motion blur is a good thing sometimes.

Try it out and share your findings!

Faster frame rates result in less skew. 720/60 shows much less skew than 1080/24 does.

I did this simple test by having a straight high contrast line in the middle of the frame and whipped fast side to side trying out different shutterspeeds in both 1080 and 720.

You might get rolling bars due to 50hz electric supply in PAL countries but outside in daylight it works fine using 1/60s.

does 24p produce pretty much same motion image as 25p (pal version) just with more complex data?

24p and 25p look pretty much identical, I dare anyone to be able to tell them apart.

Am in a pal country and I film 1080 25p 1/50s , is it better filming 1/60s ?
thanks

No, you should always shoot in 1/50s in PAL land and 1080p25
