Difficult question, which will only yield subjective answers, if any.
I'd say this though..I find a proper Julie Mango beats almost all of the newer hyped varieties. And from what I have read it appears quite a bit of today's varieties can directly or indirectly trace their lineage to Julie, if accurate, for me it's a testament to the awesomeness of Julie.
Awesome mango and tree, and growing with no fungal or disease issues for me in humid south Florida. Actually surprisingly (based on all I have read about how it fares in S. Fl) it has the least fungal/pest/disease issues of all my mango trees (graham, glenn, pickering, bombay, ndm, maha, mallika and imam passand).
Maybe I'm strange but I'm not that interested in getting the newer (zills) stuff, I'd rather get more of the classic types..I find the names of the newer varieties pretty cheesy. Maybe if I had more space I'd try to get everything, but with limited space I tend towards More 'classic' varieties.
