I tried to get into Kamihime but the questing just takes too long and after a while of getting nothing good from the gachas I decided to drop it. I will most likely drop DP too when the Zodiac shrine is finished (I want to see what Leo looks like).
Plus it seems like the Kamihime rewards aren't really that good - you're not guaranteed an SSR Kamihime. In DP you get a 20% LR ticket - that's huge for a player just starting out.
