"Better" depends on the metric. In pure recoil reduction and size/weight brakes win. In not making you go deaf even with double ear pro silencers win.
For hunting there's no question I'd prefer a silencer. Many will get a rifle down to the point a shot or two without ear pro won't cause hearing damage, and recoil reduction isn't a huge deal.
For some matches, like F Class, I'd take a brake. There's usually not a lot of barricades bouncing concussion back towards you and recoil can be an issue over a full day of shooting. I don't mind wearing double ear pro and with long barrels the concussion isn't too bad.
For PRS my favorite option is an Area 419 Maverick, which is basically a mediocre silencer with a big brake on the end. It gives the same muzzle control as a good brake, almost as much recoil reduction, and doesn't make the rifle significantly louder. It eliminates most of the concussion, which is as important as ear pro for hearing protection.
It really depends on exactly what you're doing and what performance metrics you value. There's not many situations in which I'd prefer a brake, but that doesn't mean they're inferior in every situation.
