Wow, just searching around, I found that I'm not the only one! It seems to be Haas vs. Booth...

Once I went to a park and realized the tree at the park was a (regional) avocado tree. But the avocados were REALLY high up. Like, there was no way we were gonna climb that sucker. So I knocked on a door that was right by the park, and I asked the young girl who answered if she had a stick or something we could use.
She said "actually, we do" and she brought out this insanely long stick with a little forked part at the edge that was just for picking avocados. And we picked so, so many.
You have all type of versions. Some are better to be eaten as guacamole... others are not. Here we do sweet avocados (just eat with sugar, or just put on a blender with milk).
Some of them have more fat, others have less...
Search for "Abacate pescoço". This is probably the most interesting and different one.
:)
I believe Hass is just better to export, because it doesn't spoil so easily.
Another fun fact: I think majority of people don't really buy avocados in supermarket. They are grown all over the place. Streets, backyard, parks... In my street there's like, 5 avocados trees (with each being different type). Hass is the most rare here, you'll usually find it on supermarket only...
Hass are definitely superior, but Shepard aren’t all that bad. Bit rubbery maybe :)
