What Snoog does is not optimal imo;
There is no way around Auroras in 1v1s. Ik it's easier said than done, but you'll have to get used to proper micro the entire game and push your opponent enough so he can't get gun (otherwise your Auroras are ded). Same with air, make sure to scout eventually, at some point air is recommended so your opponent can't just stack up multiple bombers and onepass your whole army.
Now that the gun range ACU isn't straight up busted anymore, I'm not even sure if picking Aeon is smth you want to do when playing e.g. ThetaPassage. I do remember some games against a strong 1v1 player where I picked Cybran and he rolled Aeon and it was basically a gg for me bc of that one. So just maining Aeon on any 5x5 / smaller 10x10 maps is smth you have to think about for a while.
My comment above is referring to high ranked 1v1 scene. For mid rank it's enough to use your mass efficient, get reclaim fast enough, pressure etc.
