Just posting to say that.... Crocune beats all the pokemon both the Sub and Life Orbed sets are arguing about.
The Life Orb Set is fine. It works well, I've seen it work well. There is nothing wrong with it.
The SubCM Set will also work because it works on every 404 HP Subber anyway, so whats different about suicune? Always a good option
Neither of the two are superior to each other. They are both completely different sets if you ask me. A subbing Cune needs its own peer edit.
Crocune is still the best IMO, simply because T-spikes and Sandstorm don't completely neuter it. And Crocune still sets up on Blissey, and beats Starmie, and will pressure stall Vaporeon and come out on top as well.
