ABS is a level up because it curls like mad off the print bed because of internal stresses, and this will cause prints to fail if you do not have a heated chamber, which is a bit of a challenge to set up over Ender 3 like printers. PETG meanwhile likes to be dehumidified under heat first to avoid excessive stringing, which requires a separate doodad, and it likes all metal hotends that do not include the usual internal PTFE tube, which off-gasses nasty stuff if heated above roughly 250°C. PLA has none of these problems. "Level up" is about printability, not material characteristics of the end product.

You think that. The people in forums who go "I never print in PLA" despite it having advantageous material properties for some use cases (it's very stiff, for example! sure, it snaps hard, but it's strong until then) do not.
Printability and usefulness aren't on the same axis, but when it comes to FDM materials, a lot of people do.
