The AWS-8Q Awesome is pretty close, too, so long as you stay in the Introtech lane. It's so effective, I have no problem using it when the tech level and Era allow for "better".
Though, the Awesomes our local campaign have set up are pretty insane in comparison, but they require DHS to handle.
A few of the Locust variants are pretty solid, again, so long as you're staying in the Introtech lane, AND keep them to Scouting duties. I usually look at if I need Machine Guns, Infernos, or pure Energy.
Once you start getting out of Introtech, it REALLY boils down to preferences in equipment, the desired Role, and possibly Quirks of the Chassis.
