Not including specials you have Laser/Plasma Pistols (including the defender), Laser/Plasma rifles, Gauss rifle, laser rcw, multiplas rifle (people claim its a shotgun but its really not), Gatling laser, flamer, incenerators, Plasma caster, pulse gun, recharger rifle, and tesla cannon.
Consider how guns is in the game right now. If you want a sniping weapon you tend to start with the varment rifle and move to hunting rifle, sniper rifle, anti material rifle in that order. Problem is, if you really like a long range plasma weapon, say a rifle, thats all you really have. You dont have varying upgrades of weapons as the game moves on like with guns. You also lack niche style weapons like a silenced SMG, pistol, or sniper rifle or shotguns. Energy does have more effective heavy weapons and with the addition of energy weapon friendly perks its getting better. However right now we need a much larger selection of energy weapons and energy weapon mods for it to be on par with guns
My biggest complaint about them right now is no close quarters or silenced energy weapons or mods to make said weapons
