I think the main question here breaks down to chord function.
If you are in the key of C then the C is the I chord and the F is the IV chord which is generally a "tension" chord. In this situation pedaling on the C emphasizing the fifth of the chord brings out that tension.
If you are in the key of F then F is the I chord and the C is the V chord which is setting up the classic V-I cadence. In this case pedaling the C probably isn't the best choice.
In a nutshell to quote Bootsy Collins, "It all depends on the angle of your dangle baby."
