Spectre might be taking over that #1 spot, but for things like Fortress waves I don't think even it can displace the Elite Mega.

What I find is that I use more different units as I level higher. At lowish level I recommend maxing out Cobras and working on Megas, get Hellfires when you can, maybe Hellstorms. Rocket buggies level quickly, can instant repair, and can be great for nuking a tower that you'll otherwise take longer losses getting. Unless your tech centre is idle while waiting for other buildings to upgrade, I'd skip other tanks and push for Megas. HG's, ERM, or Hercs work for AA and let you not have to use Tech Centre time on Gats until later since the Academy load is much lighter than the TC. I still haven't found the TC time for the Hellstorms I got several events ago.

As you level up, Lasers become useful for the Plasma resist, Razors for the stun effects. Some high level even like Paladins and Rhinos again due to range and quick repairs. Valkyries are very useful as are Gladiators and Shock tanks.
