I love them both but here are some interesting thoughts from Martin guitar clinician Diane Ponzio and why she chose Mahogany for her signature model.

“Recently, I learned firsthand that dwindling natural
resources and increased demand from other industries has
cast a threatening shadow over the future supply of
genuine mahogany.”
“I am convinced that genuine mahogany will one day
approximate the rarity of Brazilian rosewood.
Mahogany instruments sound much brighter
than their rosewood counterparts, and the
clarity is rich and distinct. It is for these
reasons that I chose genuine mahogany
for the back and sides.”

Don't forget this is a person not only with access to the entire Martin range but also gets to travel the world demonstrating them.
