Regarding shirt collar size, should I err on the side of comfort (looser) or presentation (tighter)?

I’m debating between a 16″ and 16.5″ neck, obviously a small difference, but I’m wondering if it makes a difference in presentation to others. The white shirt is 16″ and the light blue is 16.5″ . Both are pre-wash, so I’m wondering about shrinkage too.

I kinda obsess about small details, but if I’m overthinking it, just let me know.
