That is however far from the only consideration when it comes to what is best between +5 prr and 30 hp. Mitigation increases the effectiveness of your healing, which increases your survivability (your "sustain").
Its not just how large a hit you can take it is how much damage you can take before mitigation does its reduction.

The fact that mitigation effectively increases the efficiency of your healing, is not a factor in determining EPH it just means healing you is easier then healing the 0% mitigation massive hit point pool alternative tank. There survival is the exact same other wise and with limitless SP in this game its not really a factor at all.
