Yes, have a Prusa also, and always use the textured plate for PTEG, and the smooth plate for PLA. One time I forgot to switch to the textured plate when printing PTEG and it stuck so hard I ruined the surface of the smooth plate while removing the part! The other side of the smooth plate is still in good condition, so the plate isn't totally ruined, but that was certainly a lesson for me!
Now I'm more careful to always use the textured plate for PTEG!
