LE gets blued/park finishes because they are cheap, not for "concealment" or finish durability. FWIW, I have never found myself gliding from shadow to shadow, attempting to close with my opponent head-on...only to be given away by my chromed slide!
Chrome is hardest, and most durable.
Polymer (NP3/PTFE or similar, possibly over nickle or park are second, but somewhat higher in corrosion protection)
Depends on you, as well. Some folks have more acidic/basic sweat, which can be a real corrosion problem.

NP3 is a (N)ickel (P)hosphorus coating that is chemically deposited, along with a small amount of teflon.

From what I can gather, bluing will have the shortest lifetime in a harsh environment, and hard chrome one of the longest, with the polymer coatings like GunKote and Duracoat somewhere in between. I do not know where NP3 falls in this range.
I would go with chrome.
