Fourth rule… painters tape as bed surface will save your PEI sheets and holds PETG really well.
Or G10/Garolite
Comment on PETG is just as stringy as I was told

First rule of petg is “dry your filament”, second rule of petg club is “dry your filament”… Thrid rule? Nope, it’s “store your filament dry”
Jokes aside, other things you could look at:
- nozzle, how worn is it?
- calibration tests: did you do a temp tower? Calibration cube? Retraction test?
- The vertical surface doesn’t necessarily have that appearance as a result of wet filament. In my experience, wet PETG will result in more random variations than that. It looks too regular IMHO, is everything that should be tightened actually tightened?
- have you calibrated the extruder steps?

Or just use a textured PEI plate at the proper bed temperature. There is very little need for special adjuncts to print PETG.

I would bet on retraction here. Dial that in and 90% of the stringing goes away.
