Which Mass Effect game has your favorite gear?

It's a hard choice between ME2 and ME3 but I have to go with ME2. They messed with too many of the weapons that I loved in ME3 by making them smaller or weaker overall. Those being...

-Claymore (I loved the larger ME2 version much better)

-Geth Plasma Shotgun (Just didn't have the punch it use to)

-Mattock (Felt ALOT weaker in ME3)

These weapons were always a staple in any of my builds.

It’s a tough race between ME3 and MEA for me. I love the Mattock and GPS and to a lesser extent the Locust in ME2, but in terms of overall variety of its weapon roster and armor options, frankly, it ain’t got shit. ME3 is a space marine gun nut paradise by comparison. I love the weapons I can equip on companions(James with Typhoon or Garrus with Black Widow) and I have my beloved Harrier. MEA’s crafting system’s won me over, but the fact that companions cannot be equipped with gear of your choosing makes ME3 the winner. In terms of armor, I prefer MEA overall with ME3 rounding a close second. I’m not a fan of the leotards of 1, and I hate anything other than the standard N7 armor in ME2. 

I find that customization is hamstrung in all 4 Mass Effect games by tying your appearance to stats. You might like the look of that one armour, but the one you don't like has vastly superior stats for your build so now you have to choose.

Andromeda was set up to actually break that if it had let us craft armour with stats independent of the appearance of the armour, but unfortunately they stuck with the predefined stats.

Beyond that I actually do like the look of the armours in ME:A. It feels a lot more varied than ME2 or 3's armour appearances.

That's the way I feel about the ME2 Claymore. Shepard wielded that thing like a beast!

Same.

I picked ME3 just because:

M-7 Lancer: My favorite gun in Mass effect to date.

And

Blood Dragon Armor: I like the look and the description behind it. Also, with Vanguard I can pretend to be a charging knight!

I had forgotten that the Geth plasma shotgun was in ME3, because you don’t get it until the final Rannoch mission 

At least the Mattock still had some punch in ME 3, it feels really weak in MEA and unfortunately the Claymore and the GPS didn't even make the trip through dark space. 
What I really miss from ME 2 is it's version of the Locust.  The only SMG I ever really fell in love with.

The Scimitar was another fun shotgun in ME2.

ME2 thanks to Cain. Nothing like a nuke strapped to your back. No heavy weapons (save for an occasional hydra or something) was such a let down in ME3.

Gotta say ME3 because I could equip my teammates with greater variety. It really added value to the story, too. For example I was always a shotgun fan and didn't get into sniping even though the Javelin sniper worked like a dream. So when I invested in some very expensive guns that I didn't even use, it felt like my character was being generous towards his or hers squad members.

Some of MEA:s armors were very beautiful and well detailed. N7 and the one model which had light stripes on it, were defenetly gorgeous. However the guns were missing something. They didn't feel as powerful as in the old trilogy. I missed my supressor gun from ME3 a lot, and claymore and even eviscerator. Loved Carnifex heavy pistol, too.
Got it from Mordin, ended Reapers with it.

I must be the only one who wasn't huge fan of heavy weapons except the ice cannon one. It always felt clumsy to change between the big and small guns. My Vanguard Shepard didn't have time for that.

I think I have to vote for ME:3. I loved the Recon Hood, it featured the best and most realistic armor of the entire series -the Hahne-Kedar- and last but not least my favorite two weapons - the Geth Javelin and the un-nerfed Falcon grenade launcher.

The ME:A Heleus Defender armor was pretty nice though....
