Adaptive query execution and CBO

I asked this question while ago on StackOverflow but got no response, so
trying here:)

Whats your experience with using adaptive query execution and CBO? Do you
use them enabled together? or seperate? Do you experience any issues using
them? For example Ive seen that bucketing doesnt work properly (sort merge
join happens) with adaptive qe enable.

Thanks

Tom
