Ward of Dawn > Stormtrance/Radiance > HoS > Nova Bomb > FoH (in PvE at least) Titan melee has less range, but has the option to charge faster via overload and stoke the forge and has increased range when not charged. Thunderstrike has less damage as a tradeoff for it's increased range and scorch's most powerful effect increases cooldown time. Meanwhile, titan melees typically have more potent effects such as melting point and super fast reload speed with an overshield.
