25% more HP isn't superior to 20% less damage taken. To compare those you have to consider effective HP.

WAR gains 25% more HP, which translates directly into 25% more effective HP.
PLD and DRK take 20% less damage, which also translates into 25% more effective HP. Grit and ShOath makes it so you can receive 25% more unmitigated damage.
