Br or silver trumpets?

I'm trying to choose between a br Bach Stradivarius from the 1960s that was recently completely overhauled and a new silver B&S Challenger. Both are professional models that are easy for me to play. I'm an amateur player who primarily performs jazzy church music in a group of about 10-15 people with at most two other trumpets. Which is more versatile: silver or br?
