Make the choice from the job
Compare heat exposure, impact, surface finish, and whether the part is a display object or a working object. Do not choose PETG only because it sounds stronger if stringing and dimensional fit matter more.
What people often miss
Printer condition, material formulation, model geometry, orientation, and post-processing can change the outcome. Treat a comparison or troubleshooting step as a decision framework, then validate it on a representative print.
Use the workbench for the numbers
These tools help turn the decision into a material, cost, dimension, or time check without pretending that one generic setting fits every machine.
