It is that the PA is far larger than it's competitors and therefore it's better... When it comes to rads the size of is quite a huge factor regarding it's performence. Ofcouse design matters, but size is, if not, more important...

Could you please explain further your statement below:
Cooltek/MCR = 12fpi, BIX (high cfm rad) 12fpi and nearly as thick as PA. So basically, a Cooltek/MCR as thick as a PA = HE, BIX.

According to Hardwareluxxx the Cooltek is 34mm thick and the PA 60mm thick..

No, not really.

PA is under 10fpi, so it *HAS* to be bigger or it woudlnt perform very well.

In the same way, 12fpi rads designed for low-cfm cant very thick, or they pose too much air resistance, and you end with a BIX (which is 12fpi, and about as thick as a PA) which isnt suitable for low-cfm.

And the GT is 30fpi, so that even more xtreme in that sense.

So no, theyre directly comparable. Each company made their own choices viz. fpi and that decides how thick the radiator could be, and vice-versa. And each company made their own choices viz how much extra stuff they wanted on their rads - inbuilt shrouds, bleed valves, fan spacing.

Of course the PA is going to be bigger and heavyer, its fpi is extremely low so it has to be longer and have a thicker armature or you can twist it with your hands, plus its got a 5mm inbuilt shroud.

The GT is the other extreme, its designed to be extremely thin, and has no inbuilt shroud so its obviously going to be very light.

Just because other companies dont include the same features you cant say theyre not directrly comparable, thats like saying you cant directly compare an A64 and a Conroe because one has OoO read commands and one doesent.
