My own firsthand experience points to EW relying on crits to kill anything. My laser bolts bounced off of everything when I didn't crit but they killed everything in two or three shots when they did. Guns at the same skill level don't have that problem.
EWs can crit. Guns can crit. If EWs require you to crit to match a gun that doesn't crit, then the answer to the TC's question is, "yes, EWs really are bad".
Anyways, to the TC, there are only 3 energy weapons that can
match the best guns: the Plasma Caster, the Gauss Rifle(+unique variant), and the Multiplas. All three happen to be extremely rare, so you're stuck with crappy weapons for a long while unless you know exactly where to find them beforehand.
