Another "which is best " question,,, again, as with anything,,,,it depends on the gun.
From my experiences the Krink style one is great for SBR applications sense it captures extra gas for proper cycling. On a regular length barrel I have had really good results with the AK74 style ones. They'll give you the length you are looking for and they have been very effective on anything I've used them on. Must be why they use that style on everything from AK's to howitzers !!!
I have the CNC Warrior ones on 2 of my AK platforms, and 1 on a VZ58 and they are both fantastic. I very much like there products, good quality, fit, finish, and reasonably priced compared to some of the maul ninja flashy stuff that sorta works and is to expensive.
Not much of a list, I know,, but those are the ones I've found that really work and,, work well,, and are affordable. Breaks don't have to cost >100 bucks to work and have fancy scallops machined stuff all over them ect. The CNC Worrior 74 one was in the 20-25 buck range and it works better than any other I've used. I haven't tried a hundred different ones and just stuck with the CNC one sense it worked well, so I can't speak for every brand out there. But after trying the CNC Warrior ones,,,no need to shop further when you find something that works. But I did go through lots of different ones before I tried the ones I have now, maybe 10-15 different brands/styles. The 74 type just worked best for my applications.
A friend and I even screwed one on a x54R Mossin he'd threaded and it worked even better there than on my AK, guess the higher pressures and extra gas make them even more effective on that one.
Hope that helps some,, the 74 style is my preferred brake for most uses. Remember ear plugs though,,, breaks make the report louder for the shooter most of the time. One downside to breaks.
One funny thing I did notice on my AR platforms though, I have a Bushmaster with nothing on the barrel, and a Sig AR with a birdcage type flash suppressor on it. The Sig is half as loud ,,, that Bushmaster throws a flame 2 feet long and as big around as a large pumkin and the muzzle concussion is respectable, not so with the Sig with just the flash hider. There's way more of a difference than I expected.
