Which 4-way split is better?

===A===

  1. front squat, bulgarians, RDLs, leg curl machine, calves
  2. bench, incline DB bench, overhead BB press,
    triceps, calves, abs
  3. bent-over BB row pinkies-at-rings,
    lateral DB raises, reverse pec-deck (rear delts), calves
  4. chest-supported Hammer Strength underhand row,
    assisted pullups, biceps, calves, abs

===B===

  1. front squat, bulgarians, RDLs, leg curl machine, calves
  2. chest-supported Hammer Strength underhand row,
    assisted pullups,
    chest-supported selectorized machine row, calves, abs
  3. bench, incline DB bench, triceps, biceps, calves, abs
  4. overhead BB press, reverse pec-deck (rear delts),
    lateral raises, calves, abs

===DIFFERENCES===

“A” has bent-over BB row (as far away from RDLs as possible); “B”'s only rows are chest-supported.
“A” has two adjacent “back” days; “B” has one “back” day.
“A” has all presses together; “B” does not.
“B” has all delt-dominant exercises together; “A” does not.
“A” has one less session with separate abs exercise.

Thanks.

Just do “C”. For session #3, do calves at home the next morning if too tired from doing entire back plus biceps.

===C===

  1. legs
  2. chest, triceps, calves, abs
  3. bent-over BB row, all other back exercices,
    biceps, calves
  4. all delt-oriented exercises, calves, abs

I wanted to avoid putting biceps on the same day as the entire back. But realistically not worth splitting back between two adjacent days; nor worth dropping barbell rows.

Overall, my original post in this thread is probably a dumb question. Sorry about that. Thanks.
