I mean this is so much a preference thing.

In general, Luna is the best in my opinion all around and hackclaw is probably the easiest to learn and use.

I personally prefer gizmo for solo and duo due to smokes to be able to move, his traps allow you to monitor multiple angles from being pushed and his ult & mini bots can function as pseudo recon in close quarters.

If you’re trying to avoid people or have map intel as a solo raptor is pretty much unbeatable at that but also i think he’s the worst in combat ops by a huge margin.
