So we're updating SW from 2015 sp5 to 2016 sp5

I know when it came out, 2016 caused an uproar.  And even now, the UI (from seeing the screenshots) looks a bit questionable.

Wondering now, more than a year later, how are people finding it?

Are you happy with it, do you get used to it, do you even find it advantageous over previous releases?

Or would you still go back to 2015 if you could?

Any tips for someone making the adjustment?

Thanks
