I found the online routing service to be more accurate than the offline one Osmand has. Since it only uses the data connection when calculating routes, it uses less battery power than waze which has to constantly download info from the web.
That's actually a bug in OSMand. The no-U-turn data is already in OSM (OpenStreetMap) but OSMand has a problem with some no-U-turns. Nag-file na ako ng bug report sa OSMand development team: http://code.google.com/p/osmand/issues/detail?id=1729
