Healers have multiple amounts of O-GCDS, if you're making a competent Healer use GCDs just to keep you alive, it's really on the tank for not using rotated tank cooldowns properly, or DPS not pulling enough damage.

It has nothing to do with other tanks having more " heal sustains" except Warriors temporary invincible mode. A more competent tank is always going to play better with the situation than burn everything.
