What is amazing is that here in Europe, Tarocco from Italy is the best orange I ever tasted.
Much better than Moro or Sanguinelli. May be its variety in US is different, in Italy they have several dozens of  clones with different degree of color and time of maturity.

That's pretty much what I kept reading when doing my research on citrus varieties a few years back when I was going to graft a tree. Everything and everybody basically said Tarocco was the best tasting but hardly any pigmentation (read it's considered a half blood in Italy from the lack of color). Moro on the other hand, the worst tasting (for a blood orange) but it's the most pigmented, which is one of the reasons it's grown commercially, other reasons are crop size and they ripen easier/consistently. I'm kind of surprised that people here have the opposite opinion, maybe I chose the wrong blood orange to grow.

I ended up grafting Meyer lemon, Cara Cara, and Tarocco to the tree I mentioned earlier, last year I added Minneola tangelo, Tahitian pomelo, and a mandarin variety (Kishu, Owari, or Pixie. not sure what stuck). Last year my tree also gave me my first Meyer crop, this year my first Cara Caras, but Tarocco looks like it still isn't ready to flower. I only got about a dozen oranges but I think I might have picked them too soon, most were good and tasted how an orange should but the last one I picked on Valentines Day, it tasted great, it was the only one that had that "complexity" I kept reading about
