These anime are both reverse harems with plenty of colorful male characters interacting with the female main. The school setting makes them more similar and they follow the same format of having episodes dedicated almost exclusively to one of the boys. Fans of one will probably enjoy the other.

Blood+ is a vampire-centric, dark shoujo story with shounen tones, while Uta-prince is your standard pretty-boy reverse harem fare, with a musical twist, but both have similar dynamics. They both center around a regular, high school girl who starts off more or less normal, and they each embark on a journey (literally in blood+, metaphorically in Uta-prince) to rediscover themselves, their goals, and find inner strength. Both stories are very different, but the core meaning behind them is the same. Plus, both have exquisite bishounen, to boot.
