I am absolutely Langda (Maldah) fan. I have 12 trees of it at my home. Other varieties I like Bombay, Gulabkhas, Sinduriya.
But, I can tell you I tested Alphonoso, Dasahari etc. but none of them come close to the quality of Langda.
I suggest you all try this Mango and tell your experiences here. You can get Langda now even in Pune. We are getting in Bangalore although very pricey.
