I prefer 3LW over Red Death, but that is mostly based on sight preference. 3LW and Messenger are very close base state-wise, but I don't have the Messenger to know if things like recoil pattern and base Aim Assist are different. Obviously, getting an Adept Messenger with burn of choice is preferable, but that is just for certain PvE opportunities. I don't particularly care for my 3LW in PvE, I use Oversoul or Bad Juju if I'm using a pulse rifle. I'm only voting 3LW because I prefer it over Red Death.
