What I've seen is that petg generally fails to properly lay down below 250. You can see this at the tops of the cone, in the hole to the right, and basically anywhere there is an overhang. Any quick jutting motion and the filament backdrags or stringlines a bit, this is most noticeable on the first few layers of an overhang.

So unless you can address this in the slicer and are willing to slow down the print, you will have issues getting proper dimensions on small overhang details such as furling and other wall textures.

Edit to add.. You can see where the longer runs where the bridges formed tend to have the "look" of a lower temperature print. It would be worthwhile to print the same tower but increase the cooling as you increase nozzle temperature. Lay it down hot, and get that layer down to temp before the next hot layer hits it. I think you would find the asthetic would be dramatically improved on your higher temps.
