Simple example:

This the highest Item level PvE trinket I could find for this tier
http://mop.wowhead.com/item=84942
http://mop.wowhead.com/item=84937
These are the 2 highest PvP trinkets I could find but there could be even higher potentially, even with the 300 lower base strength than the 509 one (which is essentially a heroic hardmode end boss trinket) they are still considerable better as the procs/on use outweight the haste by a huge margin, unless a non base stat proc is massive over budgeted then the PvP trinkets will likely always come out on top. The other gear will be comparable but lower item level so will only be decent depending on itemization or your current progression level in PvE, also weapons are still missing an extra secondary stat (only have str, stam, res, crit), I don't mind PvP stuff being usable or even very good, but it's a little odd having trinkets that much better only from PvP as it kind of makes the entire PvE trinket design worthless atm.
