Whats the best brand?

According to Consumer Reports Mag–for the upright, here they are (all of these are best buys)–Kenmore Progressive, Eureka Boss Smart and Kenmore Progressive 36932. And for canisters–Hoover Wind Tunnel, Kenmore Intuition and Kenmore Progressive 27514. I have the Eureka and it works just fine although a bit loud. Hope this helps!
