Question about Bennett Alphonso

[FrankDrebinOfFruits]

I can find very little information about the variety Bennett Alphonso beyond "its better". Is that more productive, more disease resistant?

What about a taste comparison between Alphonso (Ratnagiri) vs Bennett Alphonso?

Update:
This article also spells it http://www.themangofactory.com/history/1493/#sthash.0PGleM6m.dpbs, and seems to be written long ago.  I wonder if there is more up to date information.
