Brake Lever Return Springs or No

Campy Ergo levers have no return spring in the lever and Shimano
levers are sprung.

Would using a Shimano or other sprung lever with Campy brake arches
make any difference in actual brake function or feel of the brakes?
My preference is to have very solid feeling brakes.

Right now, I'm using Cane Creek SRC 5 brake levers with DA 7403 brakes
and I want to sell those and switch to Campy Chorus, front and rear,
dual pivot brakes. The 7403s look and work great but they are worth
more to others than I. The preference for Campy in this case is
subjective only.
