As an NM developer I'm interested in why it doesn't work well for you.

This part is interesting, but recently we've made some improvements here
if you're carrying the patch that doesn't trigger a rescan if a scan has
been done in the last 5 seconds.

Hmm; I actually wasn't aware that we could do this in the supplicant yet
(I've been waiting for it actually) and so if it's now there, I'd love
to add this capability to NetworkManager.

Have you tried --log-level=debug in recent versions of NM (which Ubuntu
may not ship yet unfortunately)?  What kind of output are you looking
for here?  There's also this:

especially the section on "Debugging WiFi Connections".
