Banding on simple print

Hi.  I printed this using Prusament Black PETG, using the prusa profile for that filament.   They are simple rollers, printed on end, printed at .2mm on the "fast" setting.  I printed a single, it looked OK, not amazing, but OK.  So I printed the next 11 all at once.  IT seems ever 1-1.5cm I get funny-looking bands where the extrusion looks little under extruded.  It is hard to see in a photo, but the bands also have these weird flat faces (like facts) periodically as you look at the object from all sides (you need the light to hit it just right).

Everything was the same between the  two prints, but the second one is pretty bad, though still usable for my purposes.

I also printed a vice that  I got from thingaverse a while back, but never got around to.  I printed this using prusament PETG as well, again using the appropriate profile.  This was was printed us the "structural" option.  It has a disappointing number of artifact... banding mostly, though these look more like ribs than under extrusions.

I'm using the latest firmware (5.0) and the latest slicer, with the latest profiles as of yesterday.  I have to say, I'm very disappointed.  I spent a week building this thing, checking, double-checking and triple-checking each step to make sure everything was just perfect.  It fired up with no problems, everything feels nice and solid.  There are no strange noises coming from the printer... first layer looks good.  I don't understand why I'm not getting prints like the reviewers do online. They look so perfect.  I was ultra-careful in my assembly, to the point of being obsessive.  The vice prints don't look any better than my mk3s+ did... and the rollers I printed look worse than anything my mk3s+ would have printed.  This feels more like a "side-grade" than an "up-grade".
