For some this could be a very hard question and for others this could be very easy, for me it's easy, which is odd considering I don't even have the armor (not approved member on VGU). My favorite it one of the battlefield ones from dragbody, I think its called CHR Recon, not for sure. Leave a comment on what your favorite armor is! Have a good day.

Either the ME2 N7 armor, which was my first ME port to NV, or the Other M Zero suit that I ported.  I'm sure people have ported more spectacular/impressive armors than those, but I don't generally use other peoples' armor/weapon mods so I wouldn't definitively know.

(that's not out of snobbishness or anything, I just tend to port the stuff I want in my games myself)

Do you use the G.E.C.K to port stuff? I have no idea about porting.

I import meshes that I want to port into Blender - from there I rig them (short way of saying, make them animate properly in Fallout 3/NV) and export them in a format that Fallout 3/NV understands (.nif).

Then I load the mesh in Nifskope to apply finishing touches like additional textures.

From there I use the GECK to place the items in game, like in a chest that the player can loot.

Oh my that will take me a while to learn. Thanks!

It is a lot to learn yes. I recommend starting with simpler things like weapons, which are actually really easy to port in some cases.

Ok, thanks.

My favourite is probably Dragoskin tactical armor, always have it installed on every play through!

As a huge Battlefield fan, I love the BF4 armors from dragbody. Unfortunately, the BF3 armor make me invisible.

Ghost armor from SC2... if playing a modded game.

If not, I do like the assassin suit from dead money. Stealth suit from OWB isn't too shabby either.

Edit: Topic moved to Fallout Discussion.

With Mods?
Male:MGS3 Tiger Strip camo with Naked Snake face mask with eye patch.
Female:T6M Combat Uniform, Waste Land camo.

Without Mods:
Male:T45d Power Armor.
Female: Assassin Suit.

ADAM - A Definitive Armor Mod is my favorite.

Base game:
Enclave Tesla armor

Mods:
Male: Willhaven armors
Female: Combat Dress (or Battle Dress, can't remember the exact name) from Liara mod.

Vanilla: Legate Lanius' armor. It's beautiful as well as unobtainable, maybe it's the fact that I can not get it that makes it so spectacular to me!
Modded: Modded side that's tough since there are so many amazing armors made from scratch as well as ported from other games. I would honestly have to go with either the Halo 4 Master Chief armor ported from... Call of Duty, or the t45-d power armor. It's lore friendly and depending on which version you use your helmet looks very spiffy as well as like it can eat children.

Call me a dreamer, but I love any armor with a western feel to it. Like the gunslinger armor or drags marston outfit. I wish there was more cowboy mods out there or maybe some indian ones. Because Vegas has that whole Wild West theme going on ya know?

For fallout 3 i use the DC Ranger arsenal , i can't remind which armor but it was one of the heavier armors and for fallout new vegas I use the NCR ranger veteran armor alongside ADAM to improve the textures , this is probably a very common thing like people using the brotherhood power armor in fallout 3.Also quick question does anyone know any mods that add the pads to the hands for the ranger vet ?

For base game New Vegas I like to use the Remnants power armor I just love the look of it.

And for modded any armor from the TGs armor collection.

I play Fallout 3 mostly and I use James vega Body form mass effect series by dragbody and bits and bobs form other games as additional atachmenst like Resident evil bullet proof vest, BO2 granades and, shells etc. you can see it on this image, just ignore the gunz just a little mod Im working on:

Spoiler:

My favourite armors are:

Vanilla:
- Gannon family Tesla armor

- Chinese stealth armor

- Elite riot gear

- NCR Patrol Armor


Mods:
-Crysis Nanosuite 2 by Crytek

If I had to choose from vanilla game, I would pick the Desert Ranger Combat armor. If I had to choose from mods, I would have either the MK117 prototype ODST armor, C-51 Razorback, or Legacy of X-13 armor mod.
