Spiritual weapon spell

[Nox Ffred Dragon]

Shadowheart is level 6 and when I cast Spiritual Weapon I get the open for level 2 or level 3. I tried both using the greataxe and in each case the damage, hp, and turns before expiring were the same.

Does anyone know if there is a benefit to using a level 3 slot or is that option just there in case you are out of level 2 slots?

Thanks!

Upcast: For every 2 Spell Slot Levels higher than the original, the weapon gains HP 8 hit points and deals an additional 1d8Damage Force damage.

Yes, but only every 2 spell levels.
