The buttons look better close together, almost as if they come straight from
the early 90's.
To be honest, I still prefer the minimalist beauty of Trisquel's current
window border, but the Trisquel Elementary them is otherwise a strong
improvement.
The Trisquel X-elementary icon set no longer has the Apple logo on the
desktop icon. It now shows a triskelion on a Trisquel-like backdrop. Arder
also made other neat improvements. However, other icons, like the Documents
folder icon, appear almost identical to those of MacOS or may even be
directly ripped off, so those should be changed. You can download the latest
