There's a Pistonheads thread about this, and I think it concluded with the person going to an experienced retailer of all the different brands in the vacuum world.
Anyway the conclusion for battery-free models was that although the build quality is crap and they last 5 minutes nothing touches a Dyson for actual cleaning power. Sharks and the rest are simply not as good. But they are mostly better built and more repairable.
For corded models Miele are the best if you have things like animal hair to collect. Henrys are great if you have rubble and so forth.
