We still use 2014 here at work, but we will be switching to 2016 likely sometime this year for the new multi-threaded DAG.
2015 should work ok, just make sure you’re up to date on your service packs. 2015 service pack 5 should be the most stable 2015 build.
I found in general I was getting crashes in 2015 lots due to scriptJobs, but the service packs helped.
