Be aware that both will most likely sooner or later suffer from screen tearing you mentioned. Although it's quite easy to fix you need to open your watch. So if you don't have the suitable tools or your fingers are all thumbs you might want to stay away from these and go for the later models which don't have this problem.
Additionally more and more owners of PS are reporting of exploding batteries, resulting in serious burns.
IMO yes. I have both a PC and a PT but if I had to buy a watch today, considering the prices i'd go for a P2+HR.
OTOH, just for testing purposes go for the cheapest PC, with this full-featured smartwatch you won't get more bang for your bucks (somtimes less then $20 on ebay!).
And please, don't listen to Andrew48, he's talking BS whenever he starts typing
