Thank you for the input, you are correct I'm fishing for opinions especially with my second question. But I was also wondering if there's some unwritten rule for the particular case of skirting around single board walls. For example, when i installed laminate i had some big gaps around the door frames. Not knowing much better I trimmed it out with QR, later finding out this is sacrilege by more professional standards.
This has been a drawn out project so I think I got used to the look without quarter round. after seeing it a second day it's starting to not look as strange (to me).
