I am a defender of neither. However, they have Worm Gear type clamps that have sort of a springy Sheet Metal coil inside of the Clamp that evens out the pressure and at the same time prevents the Hose from squeezing out of holes; but cost more.
NAPA sells them and I used them when I replaced only the Rubber Hose on My Oil Cooler Hoses.
When I changed the Oil Cooler Rubber Hose I used tne Euro Norma Clamps (eBay) on the rear end of the Hoses and Oetiker Clamps on the front end of the Hoses.
In My notes I have the Spring type Clamps as you describe as E Z Clip Hose Clamps. But they show a special Tool that lookes like a Nail Nipper to squeeze and lock the Clamp on the hook.
The more obvious thing is that the Worm Gear Clamps have a larger range of sizes they can camp onto then the Spring Type Clamps.
In the pic is a shielded worm gear Clamp and a Norma Clamp. The Norma Clamp has the outer edges rolled/bent outwards so the edge of the clamp does not cut into the Hose and the hump has a sort of triagular projection in an attempt to even out the prssure.
The shielded clamp (you can see the coiled sheet Metal liner inside) is one of the ones I used when I replaced the Rubber Hose only on My Oil Cooler Lines. I replaced them with the Norma Clamps.
The Shielded Clamps worked fine but I used 2 Clamps on each Hose end and and the Shielded Clamps were crowded together. The Norma Clamps do the same job but the clamp bands are not as wide so that left room to space Clamps better.
