Best light machine gun to level?

[Atticus Batman]

I, personally, think the Thunder is the best LMG in the game. The accuracy and bloom on it is beast without any rolls or mods, compared to the SAW, and the fire rate is almost as a fast as an SMG. It gets more accurate the longer you shoot? Foja, that's hot. That's a lot of crit hits in a very short time. (Batman was nice enough to trade an oj Rocker I pulled right after he got a oj Thunder just before patch. I love that gun. High cap mag, fire nano, with a recoil stock. That gun starts with 4 of 10 hitting in a single spot, and ends as a fracking laser beam.)

That would be because I am fine with the rocker. Besides it has a couple recoil rolls so it's not as bad as some of the guns out there.

I use a combination myself.
Slot 1: Syphon Yamamoto (the inherent bonus is only reload, so a Thunder would be ok).
Slot 2: Syphon SAW

Throw on the Preparedness perk and you'll never have to reload.
I lose some initial damage from using Syphon, but the procs tend to keep me alive when I'm facing down an Ark Viscera.

I'm not a fan of Rockers. The forced pause is nerve racking. Disruptors don't do enough damage, but they don't have falloff, so you could provide supporting fire from farther away.

Thunders are OK but they eat bullets faster than i drink my beers. And i drink fast

Saws with the right mods are still very reliable, recoil can be managed and they still kick a punch. Hoorah.

Still say the with overdrive and the stim to make the cooldown of overdrive active again. Pretty much can always have it up for what's important and mobs die after only a few shots to the face anyways so you don't have to worry about the bloom or recoil that badly. Especially if you have the right perks to reduce your cooldown of your EGO ability. Reload full clip, reduce cd, kill enemy, reduce cd etc etc. Pretty dang cool.
