So for a while I had a Solar Plug One.1 Fusion Rifle with the following perk options - Double Down (Occasionally spawn with more than 100% ammo) - Flared Magwell (Reload maxed out [Current]) / Perfect Balance (Stability maxed out) / Armor Piercing - Who's Next? (Kill with final round increases reload speed) The thing was a monster for the longest time and I only need Ascendant Energy for the last 3 upgrades for it to be maxed out, but then I sucked it up and bought Dark Below and not only did I just now get Murmur, but a brand new second Plug One.1 with Void Damage with the following perks - Rangefinder (increased range from aiming) - Quick Draw (Fast weapon draw) / Send It (Increased range/accuracy) / Armor Piercing - Grenadier (Kills reduce grenade cool down) NOTE: The difference between the two Plug One.1s is very minimal. The Void one has slightly better range and stability, but a slightly slower reload. Otherwise they're the exact same. The Murmur that I got has slightly better range than the two Plug One.1s (except for when the Void one gets Send it), but has noticeably worse stability and reload with the following perks: - Grenadier - Enhanced Battery (Boost magazine size up from 6) / Lightweight (Increased Agility) / Snapshot (Increased aiming) - Kneepads (Slide further) I like the perks and stats on my original solar Plug One.1 the best, but Murmur's versatility is really good to have and having the Void one covers the gap with Murmur (though I have Void Machine Guns, and yes, that's plural because I got both from engrams: MG18A Harm's Way and Against All Odds, and I happen to like both, but maybe that's a separate question). The question is then, which is best to use and which can I afford to dismantle for Ascendant Energy? (I'm starved for Ascendant materials because I've got plenty of other weapons that need them such as the Vanquisher VIII and Another NITC. If I was to try and upgrade all 5 weapons, I'd need 84 Ascendant Energy. 66 if it's just 4).
