"Live Mesh has now absorbed Live Sync, so there is no comparison anymore.
Frankly, Live Sync offered better control over configuration and a way to see what was really going on during file transfers.
I miss both of those features, and I really don't want all the overhead of an integrated software package, since the remote desktop access is a joke. I get horrible performance with Live Mesh (refresh rates of up to 15 seconds) when both computers are on very high speed connections (15Mb down / 5Mb up). Logmein Free is far superior in my humble opinion."
