Alternative melee cantrip: is it too strong?

[Ganymede81]

Greenflame blade spreads the damage out between two targets, but it does become better later.

Even if you devalue the damage of those cantrips for their wonky design and melee range, they still seem unambiguously better than PHB cantrips.

For weapon using spellcasters, yes.
