What have you guys been sporting in terms of Courier armor and weapons?

On the character I've been playing recently:

I've been using:

T-51b Power Armor + Helmet

Ulysses Duster + Mask

Vera's Outfit with Authority Glasses (My casino outfit)

Q-35 Matter Modulator

Holorifle

MF Hyperbreeder Alpha

Gabriel's Bark (I hardly use it, though)

Sometimes I carry the Arc Welder around because it looks plain awesome.

Lightweight leather armor

Raider Sadist Armor

Gobi

GRA Chainsaw with mods

Oh baby

Weathered 10 mm

GRA Katana

Assault Rifle

I'll check out my mainly-guns using character and list his items later too.

Ulysses' Duster and mask

Pushy OR Rawr's Talon OR Industrial Hand
Medicine Stick
Lucky
GRA AMR
K9000 fully upgraded
A large stockpile of Turbo, Med-x, Battle Brew and Slasher

How does the fully upgraded K9000 compare to FIDO?

I prefer the .44 ammo, but I'm not very knowledgeable about either gun, really.
