Complex Warrior Question - Proc Threat Amounts

[Hibren]

Trying to do a Deep Dive here on the amount of threat generated per proc by warrior threat weapons. From what ive seen in other threads procs here are normalized meaning all weapons are going to have the same PPM ? So in theory the amount of threat generated by the proc itself and delay (swing agro) should determine hate gain?

Starting off looking at the top end of threat weapons used here

Sceptre of Destruction - 12/18 - Decrease Hitpoints by 288, Stun for 0.0 seconds - Magic (0),

Obviously the highest threat item in the game given the dmg of the proc and the stun, but given the scarcity of this weapon on P99 Im not really interested in comparing it with the others.

(1) - Ratio (2) - 100% Haste Ratio

Jaelen's Katana - 14/19(0.7368)(1.4736) - Decrease Hitpoints by 80 - Unresistable, Lifetap

Silver Whip of Rage - 13/19(0.6842)(1.3684) - Increase Absorb Damage by 150 - Rune

Willsapper - 13/20(0.6500)(1.300) - Decrease Attack Speed 35% - Magic (0)

Trident of the Deep Sea - 14/22(0.6363)(1.2727) - Decrease Attack Speed by 10%, Decrease Hitpoints by 20 per tick - Cold (0)

Blade of Strategy - 14/24(0.5833)(1.1666) - Decrease HP when cast by 100, Increase Hate by 500 - Fire (0)

Skullcrusher of Kragg - 16/28(0.5714)(1.1428) - Stun for 4.0 seconds up to level 55 - Magic (0)

I know people consider Trident BiS MH with Jalen's OH, Im just wondering why?
Is it simply because the the Tridents proc is Cold based and resisted less than the MR based Willsapper or FR based Rage of Vallon?
Does Willsaper/Trident slow generate the same amount of hate despite the 25% difference?
Does it actually generate more threat than the rune from a silver whip or more raw threat than the +500 from Rage of Vallon?
