While my experience with binding coil goes as far as turn 2 a the moment, I have tanked all prior content with both warrior and Paladin, and i will always prefer Warrior as mi prime option for tanking on any given situation with slight preference with paladin on Caduceus.

I keep seeing threads on this forum "how to fix warrior" "nerf paladin" and while everyone takes stabs at warrior for being inneficient (how?) I can't help but remember 1.0 warrior was the tank of choice for lazy players or low skilled players, PLD being called a defficient tank, all Paladin took was some more upkeep and it became the tank of choice for experienced endgame content.

To me the case in 2.0 is simply just reverted, Warrior is not inneficient or subpar to Paladin it just takes some actual work and extra imput from the player to pull it off.
If anything the only downside it has is a design oversight, unified gear for both tanks, that is the only thing if anything they need to fix, give the warrior proper warrior gear.
