Tom, I really don't have a top 10 citrus. Some of of citrus that I think are special are Xie Shan Satsuma, Golden Nugget, Valentine Pummello, Cara Cara Pink Navel Orange, Dekopon (Shrianui),Marsh Grapefruit. Brian, got me interested in Kumquats, so I now have a Fukushu, Meiwa, and a Nagami. As I am in Colorado, I have to grow my citrus inside a greenhouse, so I am limited in the amount of trees that I can have. Therefore I wanted to be sure to have one each of the big six (Orange, Grapefruit, Mandarin, Lime, Lemon and Satsuma). For the orange I chose Cara Cara which is planted in the ground and is now a large tree. For Grapefruit, I chose the Marsh, which is a white variety and also planted in the ground. Personally, I think Marsh Grapefruit when left hanging on the tree until March becomes an awesome tasting fruit. With mandarins there are so many to chose from, but the one that I planted in the ground was a Ponkan, which is one of the largest mandarins in size. I also have 5 or 6 different mandarins in containers. Choseing a lime I first planted a Bearss lime which grew to be a large in ground tree, but I eventually cut that tree out to replace it with a Black Twig Lime. The Black Twig lime is a difficult variety to locate. I got a cutting from Joe Real some years back. It is a great lime variety. The same thing happened when I chose a lemon. I first planted a Eureka Lemon in the ground, and after it grew to approximately 11 feet tall, I changed my mind and dug the tree up and replaced it with a Saint Teresa Lemon, partly because I think it is a better lemon, but also because I personally like Saint Teresa - a great saint. I also have a Saint Dominic Sour Orange tree, which Saint Dominic himself originally seed planted the tree 800 years ago on the grounds of Saint Sabina convent in Rome. I was very lucky to obtain some seeds from that tree and planted them eight or ten years back. It is now 6 feet tall and bearing fruit. Of course when it come to a satsuma there really is only one choice when space is limited, and that is the famous Xie Shan satsuma, one of the best citrus varieties of all time, and the winner of many of the best tasting citrus contests. Lastly I have many container trees, too many to mention. - Millet
