Helping choose a book cover — which do you prefer?

I'm working on the cover design for The Answer to Atheist's Handbook by Richard Wurmbrand and I'd love honest opinions from fresh eyes.
🕯 Cover A — Dark and dramatic: candle casting a cross shadow against a brick wall. Simple, moody, mysterious.
📖 Cover B — Rich and ornate: navy blue with gold borders, an arched frame, and radiant light behind the cross. Classic and elegant.
Which one would make you pick this book off a shelf?
