Feedback 106 Chorus Demo DIY SMD Version X-Vive Eurorack

Here it is. My fully assembled 106 Chorus by Feedback electronics.
I am not affiliated w/ Feedback or this project.
Just here to give a demo.
And to give some 'feedback' from my build of the surface mount version.

How difficult is the SMD version to build from a bare circuit board?
What are some pitfalls on this build?
How does it sound with the re-issue X-Vive chips?
