macOS hiDPI retina scaling options compared

These are some photos comparing different macOS retina scaling options. All use a non-vector test pattern displayed at 100% (AAPM TG18). All photos are taken at roughly the same distance, using the same crop. Forgive the slight hand-held motion blur, and focus on these variables:
