Being the best will depend on your own taste and preference.

I'm sure you already know how to browse the forum and know how to read a thread title. Scroll those threads in the Gambling section manually and check how the community is doing a good discussion on that thread. From there, you should now see if that casino is worth trying by reading all the responses there.

On what to choose, it's now up to you. Again, read some replies on that specific thread first then decide. To sort out your selections, you can try Stake.com which you can see on my signature. Not being biased but they have already established a good name in crypto-gambling.
