Reapers vs. Any race with energy weapons would end in the Reapers losing horribly. Reapers use kinetic barrier tech just like anyone else in the ME-verse, but theirs are a lot stronger. Directed Energy Weapons cannot be blocked by kinetic barriers, therefore the Reapers only defensive systems are useless against them, meaning realistically they would be easily beaten.
