MPPT is a DC-DC converter that tracks panel output (watts output) in order to keep that output in the highest watt "range". Re-read Golden_HVAC's and 12thgenusa's posts. Watts into a MPPT = watts out to batteries. What I'm getting from these guys is look at the MPPT controllers efficiency rating to determine which unit is "best".
Which will do more amps to the battery at 13v and why?
EDIT: To answer your question directly, both will produce the same output because they're the same watt rating. At least on MPPT. Someone can correct me if I'm wrong.
