I use it. Good production to build wonders, stone and marble further boost wonders, and the tech path leads to hanging gardens and halicarnassus. The monument bonus is actually really nice. Is it overall worse than starting on mines with Earth Mother? Absolutely, but I don't have the option for Earth Mother when I start on jade. The top two pantheons IMO are Open Sky and Earth Mother. They're just a stupidly big pile of yields that scales all game long.
