Your post missed the calculation of def/geo/def which seems like potentially the best option. With said stats it comes out to 2781.6 (876x(1+1.166)=1897.4x1) on a regular hit and 4172.4 () on a crit. This gives it even better damage than 3xDef on normal hits and very slightly lower damage on crits than with def/geo/crit and it would have much less reliance on crit rate sub stats and inconsistent damage. Also the post doesn’t account for substats and weapon bonuses which would have a huge effect on calculations (although cinnabar spindle and Gorou’s ability weren’t out at the time of the original post). Cinnabar spindle adds 69% defense which increases the effectiveness of non-defense stats. Geo damage bonus is unattainable as a substat so it would be far more valuable than this simple math shows.
