If they're both Absolute levels then it doesnt matter but I'd assume durability is worse to face off against as whatever you use to attack could break or take damage instead. While regeneration wears out resources (stamina, ammunition, etc...)

I rather cut him with laced poisonous sword than being unable to cut him at all

@Tsukareta123 considering absolutes

Their attribute might apply on other aspects

Such as regeneration just, regenerating anything

And etc, prob

I think it was more about if you had to face off against one which one would be worse to fight against someone with insane durability or someone with insane regeneration.

Either two would still be pretty hard to beat

Someone with extreme regen could be comparable to deadpool or above

Meanwhile with extreme durability could mean enhanced strength

Forgor to say not could mean, but they might have enhanced strength

Since if they are durable, they may be also exert even more power

Agreed fighting both of them would be aids.

With Regeneration, you could at least immobilize them. Depending on the level of their regeneration, you could disable their legs, or use tranquilizers, which give you some opening to transport them where they could be imprisoned forever.

I'd rather fight an opponent that could die but get back up rather than an opponent that can't die at all.

Regeneration for the win!
