Funny that no one actually replied to your post :) I think because most people are thinking that Sitefinity has the best UX available. Which is of course what I think, but I see your point when you compare it to Sharepoint. My experience with Sharepoint is that it is very heavy and slow, but apparently you have another experience.
I think that despite the many clicks you sometimes have to make, Sitefinity is easy to work with and that you can quickly find your way around. As for Sharepoint (in my experience) you sometimes have too much options and you have to just do 'trial-and-error' because you don't know which option to choose.
Interesting discussion though. I do like however, some of the UX choices that Sharepoint made, so maybe we should summarize them... if this is still an active topic for you ;)
