Yes, I did.
When I add a new file, half of the sources found are by Kad, other via server. After a while naturally about 90% are by source exchange, but that's how emule works. So for me, servers aren't really needed anymore.
According to the stats 73% source exchange, 5% server, 3.5% kad.
That again shows, source exchange is the most important thing and kad and server are only needed for the first few sources. The benefit of kad over server is that you can also find sources for files that are very rare as eventually you will ask every kad client if he has that file other than via server where it might happen that a source is hid from you forever (if he's on a server not in your list and also is the only source so SE can't help).
