from the few i have tasted:
madame francine,pascual and haden.
I do not have available all the other varieties mentioned, my trees are still small and do not produce fruit yet, ( LZ, CC, NDM, Lancetilla, Maha Chanok Alphonso) out of the local varieties, the ones I have enjoyed the most was the Pascual, which is a bit acidic like an orange, which gives a nice twang to the mango flavor. little fiber, and is huge.
I didn't see any Hadens or Kents this year at the Mango festival. seems they are disappearing as farmers switch to Keitts. prefer a Kent over Keitt, but more profit for farmers in the later.
Next year I'm going to try and make a trip in the summer to Fla, so I can try out some of the much talked about varieties here in the forum. my NDM and Lancetilla, should flower this year. as those plants are big enough.
this year i only tried 1 new variety "Osteen" and it was pretty darn good, even though it was just a sample "piece", I want to try a whole one.
