You mean the Remnant VI. In my opinion the Assault turret is better. If I place it somewhere to cover a special area it stays there while the Remnant VI tends to wander all over the place often far from you attacking an animal or minor foe that are no threat to you. Upgraded with Flamethrower it does serious damage.
I decided to re-spec as a Vanguard, and you guys weren't kidding...that is a seriously devastating build. The shield regen/restoration turns you into a wrecking ball with an asari sword. The only thing I have trouble with are big armored enemies like hydras, so I usually switch to incendiary ammo. Charge/Annihilation/Backlash has been a nice mix, but sometimes I feel like I don't need backlash, and could try something else like Shockwave or Nova.
