Silver Surfer (Green Lantern) vs Silver Surfer (Quantum Bands)

Which item would make him more powerful?

IMHO, the QBands (especially if take into consideration his "Keeper" showing, yes I'm aware it's an alternate reality).

Q bands!

Silver Lantern sounds like a £Pound shop item and we all know how feeble GLs are in general.

Quantum Surfer / Silver Quantum sounds infinitely better. And thus more powerful ✅
