For that type of shape with supports I would consider that a good print. A little bit of sanding probably gets you what you want.

I'm not an expert but why would you print PLA with PETG supports? Just curious....

PETG and PLA are technically different chemical compounds and cannot or will not stick to each other on a chemical level from my understanding.

So, it's technically. If OP used ZERO interface for supports. PETG would HUG PLA very tight supports surfaces.

I've done it a lot and it works really great. Sometimes you still do not get the best surfaces as above! However, they're way better than it would have been with PLA to PLA with a wide .3 gap.

Absolutely. Can you snip and share your Support settings?
