I don't claim to be an energy weapons expert, but recently I've been playing around with a few, and the Holorifle just seems like the do-all end-all of energy weapons. This kinda surprised me because guns are extremely well balanced, with the best gun being highly subjective and dependent on your character. With energy weapons though, this does it all. It's durable as hell (literally never breaks when upgraded), doesn't waste tons of ammo (which is good, since MFC can be hard to come by), hits like a truck, fires fairly fast and has the second highest DPH of them all.
Am I missing something? Is there ANY reason to use a different energy weapons rifle? I know I could use the YCS/186 to get higher DPH while sniping and I know I could use a gatling laser for higher DPS, but energy weapons ammo is VERY heavy; I don't wanna carry even more weight, especially when the Holorifle already one-shots most targets while sniping and the Gatling Laser has issues with high DT enemies whereas the Holorifle does not. AND those weapons have repair issues, too.
The Holorifle is pretty inaccurate for an EW, its magazine is small, it doesn't have a crit multiplier(it does enough damage, however, my build is crit-optimized, so the Holorifle doesn't outclass the other weapons for me) and its rate of fire not exactly high.
I only used it in Dead Money, since my return I gladly switched back to the AER-14, while the Gobi gets into the game whenever I need a scope.
Sure, not as ammo efficient, but who cares? I have tons of ammo, you can find lots just by dispatching fiends, and you can buy lots of it. I'm a big fan of bulk ammo, btw.
Weight shouldn't be an issue, either. ED-E is a perfect ammo mule, and with the GRA and Vigilant Recycler, you even have the option to reduce your ammo weight down to a third.
My Holorifle is collecting dust, and I have no intention of using at any point in time.
