Well I think you can hear in the video that the difference if fairly small. The C-bomb lacks some of the mid range of the A-bomb but I wouldn't call that 'scooped' in the way that the Cold Sweat and Miracle Man are scooped. BKP produce a lot of ceramic pickups and out of the range at least two of them - the Painkiller and the Aftermath - have very strong mids. In general where there is the option of ceramic and alnico magnets (i.e., the Nailbomb, Black Hawk, and Warpig) the ceramic will have less mids than the alnico but depending on the guitar that can be a good thing. In the BKP range the more scooped ceramic options are often recommended for guitars with bright sounding neck materials like maple or ebony, and I think that is why the ceramic magnet was recommended to you
