Tier 10 sets dilemma: Extra armor or 4set bonus? Request for mathematical approach

So, now that a significative amount of gear from tier 10 has been discovered, I am having a real hard time deciding if I should go for the 4 set bonus or all thos yummy extra armor pieces from badges + 1 drop + crafted.

So, for the math wizards out there, can some1 please model out the differences so we all can have a clearer picture of it? Hell I would love to get it started on the math but my skills are not up to par :p

For warriors, we would need to compare the bonus:

20% of max health damage absorption every 1 minute

Versus the difference in EH and Avoidance between the 2 sets, assuming same tier for them all (normal 25).

Anyone up to the task? :D
