PETG is nice to print with. It has opposite the adhesion issues of PLA. PLA comes off the bed nice and separates at the layers if dropped. PETG will break chunks of glass off of your bed and break right through the layers. I usually have my heated bed temp set a little lower around 70C and you can raise that z offset the 0.05 or 0.1 or so from where you print with the PLA. You just do not want as much squish.
