I'm gonna try and go by order of when the games were released, but I can't guarantee I'll maintain the pattern the whole way through, 'cause I'm just that random. :/

Wolf3D: Minigun

Doom/Doom II: Shotgun, Super Shotgun, BFG 9000
Complex Doom (Doom WAD): Quad-Barreled Shotgun, Assault Rifle, Explosive Minigun, Plasma Launcher, Railgun, BFG 9000, BFG 10000, Demon Tech Rifle, Demon Tech Devestator

Heretic: Gauntlets of the Necromancer, Ethereal Crossbow, Dragon Claw, Phoenix Rod, Hellstaff, Firemace (all of them are even more awesome with Tome of Power)

HeXen: Beyond Heretic: Spiked Gauntlets, Mace of Contrition, Sapphire Wand, Timon's Axe, Serpent Staff, Hammer of Retribution, Firestorm, Arc of Death, Quietus, Wraithverge, Bloodscourge
Wrath of Cronos (HeXen Wad, I haven't seen all the weapons yet so I'll update this later): Jade Wand, Mace of Contrition w/ shield, Machete

Duke Nukem 3D: Pipebombs, Explosive Shotgun

Shadow Warrior: Katana, Shurikens, Riot Gun, Double Uzi's, Missile Launcher, Guardian Head

Blood: Pitchfork (lame but memorable), Flare Gun, Sawed-Off, TNT (all versions), Tommy Gun, Napalm Launcher, Tesla Cannon, Lifestealer or whatever that skull weapon was called (Voodoo Doll was too underpowered)

Quake: Every weapon in that game was awesome.

Marathon (yay 1st one obviously out of chronological order): All the weapons in that game too.

Strife: All ones here too excepting Sigil, I don't like guns that take health to fire.

Half-Life 2: Gravity Gun and all the other futuristic weapons. The conventional weapons in that game were just meh for me.

Portal: What do you think it is?

TF2: Flamethrower, Rocket Launcher, Pistol (it just has that chatter-y sound), Minigun, SMG, Knife

Historical: MP-40, PPSh-41, Type-100/44, M1 Garand, MG-34, Type-99 LMG, MP-5

Every other one of my favorite weapons so far was made up by me, so here's your complete list pretty much. :P

[Untitled]

Best Starting Weapon: Dark Forces: Kyle Katarn's Bryar Pistol. First weapon you get, and it's pretty good (albeit the blaster rifle had far better DPS), and sets the tone of the game perfectly.
Runner up: Quake Shotgun. Yeah, it's basically a pistol, but it sets up quake's weaponry set pretty nicely.

Best Shotgun: Doom 2 Super Shotgun. Can anyone even argue against this? It practically defined Doom's weaponry, and set the tone for the most badass weaponry of pretty much ever.
Runner up: Dual WSTE-M5s. These were pretty damn badass, with a reloading mechanism that none of humans understand.

Best Chaingun/Machine Gun: Hmm. Hard to say. Lot of competition here.

Best Rocket Launcher: Quake Rocket Launcher. This is basically the SSG of Quake and Rocket Launchers. This is the weapon that defined quake. It is pretty much the start of an era of rocket jumping (until ZDoom got here), and was generally very powerful.
Runner up: Marathon's SPNKR. Took out pretty much everything you aimed it at, and was extremely powerful, but it suffered from having a trail that was kind of silly-looking.

Best Energy/Plasma/Whatever-based weapon: Quake Thunderbolt. Pretty much the only quake weapon that could possibly be considered on level with the Rocket Launcher in DM. Also, shot frickin' lightning bolts. Only problem was that ammo consumption was kind of lel
Runner up #1: Railgun. Frickin' Laser Beams at their finest.
Runner up #2: Plasma Rifle. Would've beaten railgun, but my ears don't like the weapon.

Best Powerup: Heretic Tome of Power. While some people don't like that it's entirely counter-intuitive what this does to some weapons (the rocket launcher becomes a flamethrower?!), the whole powered-up state combined with an arsenal of unique weapons all having unique benefits made this a very interesting and powerful powerup.
Runner up: Quake Quad Damage (GEE NOTICE A PATTERN HERE): The sound of it's activation is pretty much known to everyone. The sheer power of this thing is devastating, turning even your shotgun into a cannon of death. Only loses to Tome of Power because it's actual practical effect is very straightforward - it is, in the end, simply 4X damage.

And now...

Best Ultimate Weapon
#3: Dark Forces: Assault Cannon. Bonus points go to the fact that this gets used against you more than once, by the Dark Troopers. This weapon, while not a crowd-clearer, was certifiably badass, and could deal pretty good damage. It's missiles also were a force to be reckoned with, both in your hands and in your enemies' hands.
#2: Hexen: Wraithverge. While the other two ultimates were pretty badass weapons, neither them could compare to the sheer power of raising spirits to absolutely destroy most opponents.
#1: Doom: BFG 9000. Who didn't expect this?
