Well, there are always trade offs with muzzle devices. My main criteria are effectiveness. light weight and small size and, depending on the rifle, 922r compliance. I swear a lot of muzzle brakes are effective just because they're heavy (i.e. the 4 piece Bulgarian booster / chunk).
I have tried several AK brakes for 7.62x39 -- not all, which would cost a small fortune -- and watched the videos. I haven't felt much difference between the $100 Krebs, the $50 Manticore and the $25 Bulgarian as far as recoil / muzzle flip control on the rifles. Overall, the tiny Bulgarian two slot brake is the best performance-wise.
On the pistols, recoil is negligible anyway, but muzzle flash is extreme -- singed eyebrows, etc. -- so a flash suppressor is my choice and no need for 922r compliance. Now that I have a Phantom, I can compare it to the Manticore Eclipse. I notice that the Eclipse is somewhat heavier, but the Phantom is a bit longer.
The great thing about most Com Bloc rifles and pistols is that their muzzle devices are usually quick detachable -- you can easily change from a muzzle brake to a flash hider depending on the situation, so you can carry both.
I have a 3 or 4 piece (however CNCW markets) on my Yugo M92 pistol. Also have tried the OE device that Century sells. 3 or 4 piece is much better -- but yes, I agree and have posted here previously that I'd much rather have an extra 2-3" of barrel length and a lighter weight muzzle device than having to run the heavy CNCW brake, but it does have the best overall function insofar as flash mitigation in sight picture w/ (former) comblok ammo sources. Which is why I find the 12.5" CSA VZ58 quite interesting, though I haven't yet purchased.
Open tine flash hiders have to be heavier in order to have the necessary structural integrity since each tine is independent. Some of the more expensive devices have lightening cuts down the middle of the exterior of the tines that help reduce weight -- but yes, Phantom is very lightweight relative to performance.
I don't subscribe to carry both. My recommendation would be to configure the weapon for a specific use and use it as configured always... Dealing w/ a gun w/ wildly varying recoil impulses does detrimentally affect practical accuracy in less than ideal ways.
On my RPK w/ 20" heavy barrel, I have a PWS FSC-47 which allows for both greater accuracy (especially at high rates of fire) and decent flash mitigation (given extended barrel length). On ARs w/ quality light profile barrels, I like the Precision Armament AFAB brake for overall performance, but it's far too heavy for use on guns w/ A2 profile barrels -- cheap on ARs, the A2 flash hider indexed to optimized recoil based on shooter's handedness is my preference.
