Alright, sorry for jumping to conclusions then
Ideally, run simcraft to get your own stat weights (If Simcraft is to hard to figure out for you, just take the stat values posted by Azor from Icy-Veins. Then insert the values into Pawn (Or similar/do the calculations manually) too see if any piece would be an upgrade.
There are cases where higher ilvl items will be better even though they have subotimal stats, but it all depends on what stats and how big of an ilvl difference.. The above way is the only way to know what theoretically is the best.
