I am happy for your positive approach. Lets not be all negative - SW2016 interface will hit most of us someway. I am still on SW2015 so I can not really help.
Expect to upgrade when we reach SP2 due to too many SW2015 issues. So it would be great to know what to anticipate.
Have you seen this thread: What is Really New in SOLIDWORKS 2016 (Video Series) ?
Im not a fan of the new interface, but apart from that 2016 so far is very stable for me. Some nice new stuff in there like breadcrumbs.
