Well, say no more... The armors are all good, but depends of your build and strategy. I'm playing LR with my EW build, secondary using melee and some proficiency in explosives for using mines and grenades (not the weapons). I'm using Sierra Madre Reinforced + Space Suit Helmet + Mobius glasses. I also have the armor implant and reinforced spine. Total = 29 DT. My main weapons are the laser rifle modded for sniping, a combination of Compliance Regulator + Recharge Pistol for normal combat, for melee Shishkebab and Knock-Knock, the later I use when needing to face deathclaws (or if is a larger pack I use compliance + shishkebab, I killed Rawr with this combination, didn't even need to use stealth boys or other fancy things). ED-E is carrying Tri-beam Laser for when a frontal assault is needed. I have 9 luck, Lexx mod that transform 1st recon beret into a perk and finesse (but in a unmodded game you'll need to take Light Touch). So my critical chance is 19% one way or another. Since I have Laser Commander perk and the two ranks of Set Lasers for Fun, my damage with laser weapons are enhanced with +15% DAM and +14% critical chance. For this setup Joshua armor and Courier Duster have good stats but low DT; Legion armor is heavy, I don't use heavy armor; in the end the real choice is between Sierra Madre Reinforced and Elite Riot Gear, because I need DT, not critical chance. Sure, more critical chance don't hurt at all, but I have more than enough at this point. Really, I'm spawing critical hits back and forth, almost every shot I made is one and if done sneaky is more than enough. I will go with Sierra Madre Reinforced, because my build is already done, I'm still at the LR beginning and I tailored the build for speed with Travel Light, you only acquire Elite Riot when you are about to face Ulysses, so it came too late for the party. But when I did LR at level 15, wich means I still need to do all the other DLCs and the main game, I choosed Elite Riot Gear when using guns. My explosives focused courier will still go with Sierra Madre, since critical chance means squat for explosives. And if you need more DT for explosives is better picking Hit the Deck, not an armor. So depends of how you play, isn't? PS: Two things I always carry with me, build independent: throwing knifes and some venom. Who needs silencers, neh?
