There is no comparison. Two totally different mangoes, not a renaming issue. The LZ taste like orange sherbet (with a little orange tanginess) while the PPK/Lemon Meringue tastes like lemon, no orange characteristics whatsoever. With both grown equally, the LZ is slightly bigger than the PPK. With that being said, I have seen a lot of small PPKs and ones that are bigger than "normal". All of the LZs I have seen have been fairly consistent size wise (maybe because the source has all been the same). I would keep both if you have the space, if its either/or, no question, LZ would be the choice.
I can't remember a strictly lemon taste from the PPK. I got an orangy citrus taste. I guess my palette is just not as refined.
I did not get an orange sherbet taste from the Lemon Zest. Oh well.
Let me clarify:
PPK - not like a sour lemon but a sweet lemony cream, similar to that of a lemon meringue pie. Is it sweet, yes, Is it sour like biting a lemon, no...unless you are talking a lemon after eating a miracle fruit :
LZ - I still say it tastes like a tangy orange sherbet (I did say tangy in my previous post). Maybe thats the lemon component but either way it did have a true characteristic taste of orange sherbet in a mango.
Keep in mind that one must have some "creativity" when describing tastes. To my wife, a mango is good or just ok. She does not detect most of these specific flavors. Take the Pina Colada or Gary for example, does it taste like eating a pina colada drink ? No...but it does taste like a mango with a true reminiscent character of a pina colada while eating a mango. Same with Coconut Cream, picture eating a sweet mango with a heavy creamy coconutty character (reminiscent of the flavor if a coconut cream pie).
Like murahilin said, since tastes are subjective and each person's palettes are different, some people may detect different nuances that others can't. Ask my friends and family, I have always been told I have "extra" taste buds unlike most people in that I can detect flavors that others can't (kind of like a wine tasters/reviewers, which is one "culinary" area that I have been told that my taste buds excel in).
