PAL has better resolution than NTSC

That's only true for DVD, not blu-ray.

Of course! It's all in the lines of resolution:

Horizontal rez lines:
a) interlaced - every other rez line is copied or filtered from/with the previous line of rez. Barely noticeable accept during movement, where it might become noticeable.

b) progressive - every line of rez is independent of the next, providing their own unique line of resolution (so 720p is a full 720 lines of horizontal resolution lines).

(height of image)
NTSC: 480
PAL: 576
HD: 720p to 1080i/p

Also keep in mind that you can have a 1080p transfer of a crappy print (ie: the ONG BAK blu-ray) - a HD video is only going to look as good as the source and the recording process (too much D[igital] N[oise] R[eduction] or overpass of cleaning programs to remove dirt, hairs, etc on film or not enough or not at all, like the US 1954 GODZILLA blu-ray release... blegh!)
