Which type of muzzle brake affords more recoil reduction-cylindrical with 3/4 chambers or the clamshell type???

The clamshell types typically are slightly more efficient, but given equal and proper installation, you'd be very hard pressed to feel the difference. I bet most people can't tell the difference blindfolded.

If you're after every ounce of recoil reduction, go with the professionally installed clamshell style. There are compromises with either.

I've tested most styles and brands. Installation is more critical than design. You'd be surprised how well a 1" od brake made by simply boring a 1/2" hole perpendicular to the bore tested. It actually beat most of the more expensive designs in testing.
I think the brakes made by Ross Schuler are the best bang for the buck, and they tested that way.
 
A brake can use gas to push the muzzle in various directions, i.e. the Thompson, intended to reduce muzzle rise. The only way a brake can reduce rearward recoil is by directing gas to the rear, as seen on tanks/artillary. Venting gas has the same effect as shortening the barrel, reducing the bullet velocity. Don't blame me; blame Newton, LOL!

A muzzle brake does not reduce recoil so much as it counteracts it.The action of redirecting high velocity gas flow imparts a forward load on the baffles of the brake. Although it may be true that some brakes that have ports angled to the rear are more effective than similar designs that vent at 90o to the bore, the big factors in brake performance are the baffle surface area, (i.e. the diameter of the brake if it is round) and the actual muzzle pressure of the application. Recoil has 2 components; the first being the opposite reaction to the force of accelerating a projectile to high velocity and the second being the jet effect of the residual gas escaping the muzzle after the projectile exits.

Some designers of brakes have taken esoteric knowledge of physics principles to design more effective brakes while others have just tried what seemed to make sense and through testing and development arrived at effective designs. Many of the claims made about brake effectiveness and noise intensity are simply wrong, while others are accurate about results but cite the wrong reasons for the results.

Of course these are only my opinions and I could be out to lunch.
