So, I did buy the tree and I did plant it in my yard. It was a small tree but it produced 2 fruit this past year and the fruit were good. They were similar to Oro Negro but matured earlier. Not sure if I would say it's better or worse than Oro Negro, I also have an Oro Negro tree. It didn't set any fruit recently, probably b/c I let it carry fruit as a tiny tree (didn't want to wait years to try the fruit), but it looks very healthy and is growing well.
Overall I think it was better than Monroe. Choquette is good too, so it's hard to say, maybe a little better than Choquette.
