Thoughts on Davos:
- it is a beautiful little village with great hospitality
- it is expensive as hell
- it has great climbs that might not be that famous, but don’t need to hide from any French or Italian climbs.
→ all 3 points apply to pretty much the entire Swiss alps 
It will definitely be a great event. I did Crans Montana in Valais last year and it was one of the most beautiful places I have ever been to.
With you having done AdH already, you don’t need to care about the bragging rights of having climbed such an iconic climb, so I guess Davos will be perfect.
Only thing to note is that - at least on paper - it is not quite as challenging as the other 3 day events (of 2021 also). If that’s a good thing or not, you have to judge.
Still plenty challenging…
