What differs the M6 TP version from SP version

I'm about to buy a Meizu M6 any day now.
But can anybody explain what differs the TP hardware version
from th SP version ?
From what I've seen, SP version has a improved Samsung display.
Regarding to the news "Meizu Introduces Special Holiday Prices in China"
the (what I think) newer SP version is cheaper ,how is that ? Would it not
be the other way around ?
What version is prefered ?
Hope anyone has knowledge in this issue.

Many Thanks,
Spiff
