Most stable version?

[Jean Tremblay]

Hi,
Which version of Cassandra should considered most stable in the version 3?
I see two main branch: the branch with the version 3.0.* and the tick-tock one 
3.*.*.
So basically my question is: which one is most stable, version 3.0.5 or version 
3.3?
I know odd versions in tick-took are bug fix. 
Thanks
Jean
