assuming all things were equal in terms of genetics,age, and years lifting is there a "best split" for size?

accumulated fatigue would require occasional periods where volume and frequency would have to be reduced in order to heal. additionally, there would have to be some sort of breakup into days for volume, intensity, and recovery/prehab. anyone but beginners doing the same workout 3x a week are gonna stall in months due to muscular imbalances or lack in GPP/muscular stamina.

would be better imo. recovery days would focus heavily on mobility and muscle imbalances, so a lot of things like ham/glute iso, more lat work, rear delt work, abs, neck, etc.
volume = 10+ sets per muscle group, no set below 8 reps
intensity = no reps above 5, if you're going to be doing block pulls/rack pulls or use a slingshot, do them here. a good start is working to a top set of 5 on main exercises, and then doing some lighter work after to cool down.
all upper body sessions should have a horizontal pull, horizontal press, vertical pull, and vertical press. after that, choose 1-3 fluff moves and go to town.
lower body days should have squats or a squat variant, and deadlift, a deadlift variant, or something that builds the deadlift. after that, fluff work, calves, or extra accessory lifts/abs are fair game.
