John the corners is the biggest difference. The shape is or Porsche seal corner is triangular the URO are 2 rectangular flaps that are harder to mold into the B pillar
Porsche seal corners flips and fit the crevice where B pillar meets roof with just the correct space to fit the felt seal on top with the mini screw and get it air tight
Porsche rubber seems to be more pliable and folds easier when pulling the string.
Seal installation is a biatch regardless. Hot day helps. Lube helps. Beer helps more
I own a few cars, I've done it a few times and I see the difference
