Eureka
was actually more expensive than Hoover, well a Convertible anyway.
Eureka always had a TON of models with varying features, so there was quite a range in price from the bottom to the top of the line.
No doubt though, the Eureka was an excellent performer, at times better than the Convertible. When Eureka added their Dial-A-Nap and Rugulator height adjustments, their machines were better than Hoover's 4-position Convertibles.
IMO Eureka made their best uprights from about 1969-1979, especially the 2000 series machines with their original 3.5 amp motor. These cleaners were well made, sturdy, and cleaned beautifully. They also had a flashy pizzaz to them that the Hoovers did not.
I have a handful of Eurekas in my collection, my favorite being a pristine 1972 Golden Vanguard model 2092, complete with cord reel, chrome motor hood, box top bag, and their infamous touch power hand grip. Its a fun cleaner to play with!
