Electron microscope scan comparing Intel 14nm+++ and TSMC 7nm transistors

It's worth noting that the 7nm Lg is 21 nm while the 14+++ is 24 nm, at around 12:55 mark.

At 13:08 there is a side-by-side comparison of transistors cut from the SRAM arrays of each process. Is it just me or does TSMC structure look neater and more uniform? Perhaps the comparison partially indicates areas where Intel is currently struggling with?

TSMC definitely looks neater
 
The quality of the picture from SEM depends on few factors: sample preparation, vacuum level in the SEM chamber, electronic gun adjustment and the expertise/experience of the SEM user.
