Depends on what's important to you.
The Edelbrock's are American made in their own American foundries, cast then CNCd impellers VS stamped steel. Thus cost more.
The Tuffstuff are advertised as "Built in America" as in "Assembled in America" which is truly not the same as the Edelbrock's.
I personally like Milodon pumps. They use GMP housings (China,Korea,Thailand, Japan)
but use their own internals and are up front about it, with no word play.

Of course GMP pumps are made well and 1/2 the cost of the Milodon.
