The value derived from your MR points will depend on what you need from them. Transferring to BA for last-minute AA or AS short-haul redemption will yield one of the highest cents/point value. However, this advice is worthless for someone who needs premium cabin redemption from Asia to South America.

Without some sort of defined need, one cannot offer you good advice. Unless you have definite travel plans, I would urge you to refrain from transferring points anywhere as you cannot reverse the transfer.
