PETG is nowhere near as light or heat-resistant as ABS, so it's a nice option on...

PETG has a higher density than ABS.

Its heat resistance is also not that far behind ABS.

ABS is harder to print well. Warping and layer adhesion problems could make it perform worse than PETG unless everything was tuned properly.

Yes, PETG has higher density, so it's much heavier for the same volume, exactly what the author doesn't want.

The heat resistance isn't far behind, but that still means it's behind.

Yes, it's hard to print well, but it's the best-performing material when you need light, durable material. That's the tradeoff.

It is not the "best performing material". There are several options which exceed its properties even further, but are increasingly expensive and harder to print.

Engineering is about being good enough. PETG is good enough in this case, and also cheap and easy.

Using PETG was a good choice. There's a spectrum of 3D printing materials. Not sure why you've chosen to die on the ABS hill. ABS isn't even in favor relative to ASA, FYI.
