Favorite from Fallout 3 would have to be the Vault Mechanic outfit just for the rolled up sleeves and the 'Connies' but against the albino radscorpion Winterized T51b all the way.

New Vegas whole different story. Vanilla was the Veteran Ranger outfit, Dead Money would have been the ghost outfit if you could get them (hooded and without mods), Desert Ranger outfit for Honest Hearts, X-13? suit from Old World Blues (reminded me of the prototype medic power armor from FO3) and of course the Riot outfits from Lonesome Road with the Elite being the top pick for me.

Modded FNV would have to be the concept art outfit for Lonesome Road (if only the duster would sway in the wind..) and as of now Dragbody's BF4 US Assault (cheers for that)

For me it is probably Joshua Graham's armor. It looks good, it has a balance between minimalism and just enough details, and minus the designs on the shirt is precisely what I would see myself wearing in the Fallout Universe

I always liked the goofy charm of The Mechanist armor. As far as modded armor I thought the midwest brotherhood power armor and the advanced midwest brotherhood power armor were particularly cool as well. Drag's legion overhaul was also a high light to me.

I'll always think joshua grahams armor is by far the best for me

I don't know why but I really like NCR trooper armour, even more so with Dragbody's overhaul though. It's probably the militaristic vibe I get from it.

My favourite armour to use though would probably be the winterized combat armour from Operation Anchorage because that stuff looks damn fine imo :0kay:

I actually really like the default NCR armor as well. I noticed it immediately when I first played New Vegas.

my armor would have to desert ranger armor for the vanilla armors is just looks better then the ncr one and has a wastelander feel.

and for mod armor that would have to be master chief armor from halo 4

For me, it's the Assassin Armour from Dead Money and with a bandana looks even better! Mod wise, I'd say it's the Courier Six Power Armour.

My favorite vanilla armor is the ncr veteran ranger.
My favorite mod armor is the 501st stormtrooper armor from the Mojave Stormtroopers - Imperial Armory mod by AssDuffJayKayE

Well, to me most of the games armors sucks. BUt if i had to chose I guess Id pick the Elit riot gear.
Now if we're talking modded armors I have one answer for you: dragbody all of his stuff.
VooDoo Armor from Dragbodys public release is my top 1 and this one just bringed me a lot of fun to use with my M4 SpecOps, from public release of Master_Shifu.

The Elite Riot Gear is mine.

I definitely like the older T-45d power armor compared to the T-51b. I think what I didn't like about the 51 had to be the helmet. The single slit for your vision kind of reminded me of the Cylons which isn't a bad thing but I just wasn't a fan of it.

The 'Black Devil' Advanced Power Armour MK II, Enclave Power Armour.

I love the suit, not as intimidating as the original suit of advanced power armour but it is still intimidating as all hell and very aesthetically pleasing when it comes to the overall design of the armour, it's not as bulky as some power armour but looks to have been designed with angling in mind which would cause a far greater amount of ricochets from bullets which adds to my overall immersion when I play any Fallout with the MK 2 power armour and take basically no damage from bullet weapons.

Vanilla: I guess Elite Riot Gear.
Mod: I use Drag's gear from "I am alive". Looks perfect.

This is a very tough one to answer, as not all armors in FNV or F3 reflect how they looked in F2 or F1 for that matter that being said here's my answers.

For New Vegas/Fallout 3 Vanilla - Enclave Remnants Armor (With mods you can get one pretty darn close to the original Advanced Power Armor Mk II).

For Mods - Going to have to go with TFH's 1st Recon Armor and Helmet.

T-51b armor is hands down the best IMHO

Hellfire Duraframe armour, Enclave APA MK II 'Black Devil' and APA MK I are my favourite sets of power armour in the Fallout series, they each have unique designs and are in my opinion the most intimidating sets of power armour, when you see someone in one of these suits walking up over a hill you know best to turn and run, if you value your life.

My favorite armor would be T-45d power armor

T-51b from Fallout 3. When I first found that armor via quest in Fort Constantine, I nearly shit my pants. Just something about the appeal of that armor resonates with me. If you put it on you could win a fist-fight with a deathclaw. Well, in FO3 anyway..

Modded armor would have to be Voodoo's armor from dragbody's second public release. I usually don't use armors from outside the game, but I am a die hard fan of Medal of Honor. Warfighter is no exception. They made the kits in that game as authentic as possible, you can take my word for that. I'm thankful for dragbody bringing that one to light for us Fallout players.

my favourite is desert ranger armor
