Well for boldness and their personality, my zarayunga anthonyi are my favorite... But for looks and and general coolness, it would have to be my uakarii. It's all personal prefrence, lots of people like the big tinctorius and dendrobates while I'm a more of a ranitomeya and epipedobates type of guy. Good luck with your darts and remember to always stick to a schedule when you are making fruit flies...
