These 'which mango is better' threads are pretty silly, really. The fact that one's preference is mostly determined by their culture (American coke, for example, is different to Australian Coke and tastes like cola syrup to me) notwithstanding, there's just too much subjectivity involved to denote different cultivars into categories of better than or worse than. Obviously there's going to be some exceptions, such as turpentine mangoes which are used as rootstocks.
LZ might be the GOAT in the US, but the Asian market might preference MC. For example the most popular prickly pears in Mexico are the green fleshed types--but I and many other collectors find them bland and sometimes strange tasting.
Normality is culturally bound.
