I thought the dark energy ending had it so that the Reapers needed to make more of themselves to have the computing power to solve the problem.

But if it was up to me, I'd sacrifice humans to help the Reapers. They've been working on the problem for millions of years, no way the galaxy could repeat all of that work in a century and find the solution alone. They might be super close to a solution and a human Reaper is all they need.
