Any reason you are recommending PLA instead of PETG?

I still get worse finish quality with PETG (stringing and globbing) and these PLA+ type materials just end up being as good for me while being easier to print. PLA also prints a bit faster.

PETG is, for me, always stringy. And I don't want to breath ABS fumes.

From my experience PLA is just easier to print - prints are less likely to fail and more consistent.

Also due to lower nozzle and bed temperatures, prints start faster so you can check the first layer sooner before you let the printer do its thing.

For some applications, PLA is a little more rigid. It will then fail in a spectacular fashion, but "I need you not to bend" is something PETG doesn't always perform the best for.

any reason to use PETG instead of PLA? PLA is plant based, in theory bio-degradable, while PETG is produced from crude oil.

Not the person you’re replying to, but I can see the appeal of PLA. It has more color options and prints way easier.

I personally run all PETG because it is ultimately better material post-print, and once you understand how to print with it, it’s not really much harder to deal with.

The day I discovered that I should just run my dryer with the PETG inside while printing was revolutionary. Of course, that requires you own a dryer that allows the filament to print while it’s inside.
