Did some testing with lvl 3 ants. It seems like they are actually a bit more food efficient due to reduced hatching costs. For most levels, this won't matter, as there's too much to gain from having more lvl 1 ants, but for 3.X the lvl 3 majors: (1) are far less costly at lvl 3 since they're so strong, especially with damage resistance on T majors and AoE stun on S majors; (2) will be needed soon for the 3.X challenge; (3) can handle a lot of the strong AoE in the jungle from rove A beetles and DBCs.
