Bambu Double-Side textured PEI vs Textured PEI

I see that stock Textured PEI plate is a bit thinner and also the texture is not so rough as Double-sided Textured PEI.
Is there a difference in stickness ? what are other differences in practice ? also I can see that double-sided plate is a bit thicker - is it a problem for P1S or for Bambu Studio? (I choose just Textured PEI plate in settings)

(of course I can see finish on my models a bit finer on the stock textured PEI plate)

also I can see that my PETG sticks less to stock textured PEI, pieces disconnect from it when I just take it from hotbed almost, and really good to Double sided Textured PEI - to the point I have to use metal blade to scrap/remove some pieces.
(both new and cleaned with dish washer liquid)
