I've noticed it's a bit harder to get the daily or weekly bonuses at Mbit (maybe it's just me struggling). But the cool thing about Mbit is they give you bonuses right away. On the other hand, with Bitstarz, you usually have to wait until the next day or week. For example, if you deposit 1.5mbtc on Mbit, you get 30 free spins right away, but with Bitstarz, you have to wait. Still, it's a nice bonus, especially after spending all your money super quickly on games with buffalos or candy falling from the sky.
