Turrets VS Guardians

The common thought is that turrets are better to defend your base then guardains are, but it seems when I help in an attack a guardian hits me just as hard as a turret.

Does anybody know what the damage/defense difference is between a turret and a guardian?

Turrets seem hit harder but have less nano resist/evades than conductors. Least that what my experiences seem tell me. One being more defensive and other being more offensive item.
