I did a quick test on an SQL Express 2016 instance and can confirm the differences are not as drastic as they use to be.
SQL Server 13.0.2151 (express)
16 Gb Memory
Windows 10 enterprise (reported as windows NT 6.3 10586)
3.6 GHz 4 core, 8 logical
The timing results were:
109102Statistics Time Baseline
13121470Statistics Time Function
1300Measured Time Function
110Measure Time iTVF
104Measured Time Baseline
I've the the differences between both the CPU and Elapsed measurements.
