A couple things to be aware of. Everything else being equal, a larger lamp has greater light output than a smaller lamp. So a 7" Hi/Low will slightly outperform a 5 3/4" Hi/Low. And a Hi/Low lamp is, by design, a compromise between the requirements of a high beam, and the requirements of a low beam. However, the high-beam only on a quad setup is designed specifically for maximum performance as a high beam, which is to say they are very impressive.
In a nutshell, if you upgrade all four 5 3/4" lamps of your quad system, you may notice a bit less light on low beam compared to a 7" H4 setup. Still excellent, well-controlled lighting. Switching to high beam will amaze you. When I had four Cibies in my old '66 Corvette, the word I used to describe the high beams was "dazzling". I still miss that car.
