Page would be in my top 5 early citrus, but not overall...as for dekopon if you like citrus that trends towards the sweet side then it would probably be worth growing. As for me personally, while I appreciate it's rich flavor it's a little too sweet for me as I prefer a more well balanced citrus. I know that it's many people's favorite citrus though and I can understand why even if it's not mine. You should take your own preferences into account when deciding on whether to grow it or not.
