I'm EvoSpeed SE 2015 FKW (Evopower SE pads, EvoSpeed looked naff.) And i rate the bats (Though most seem to rate the softs over the bats)
There shouldn't be any difference in the profile between the different grade, just aesthetics.
My SE does look very nice, but it wanted to be for the RRP (£600 in 2015!) I waited until Black Friday and got mine for £200.
I've also got an EvoSpeed 4 as a net bat, as you'd expect it has 5 fat grains.
Correct about the NB link, I've always assumed Sondhi made but nobody on the forum seems to be able to confirm the stamp mine has on the binding.
If money is no object and you really want Puma, I'd wait for next years stickers, much nicer than this years.
