Personally, in production I prefer being backlevel.

In general 4.16 is fine. Been on it since April 20. Aside from a
slight init delay on a SuperMicro H8DM8-2/H8DM8-2 dual-quad-core
Opteron box, there have been no issues.

There the only issue there is an init issue with:

perf: interrupt took too long (10078 > 2500), lowering
kernel.perf_event_max_sample_rate to 19800

I see that all the time ? When I googled it very recently, I think the
consensus was not to worry.
