ive used both, and own both. the black max is tiny compared to the stealth, if size is a consideration. the stealth has a far superior handle. the black max also is labeled as a 6.4:1 but it feels like a 5:1, not sure why. they are both smooth, cast a mile, and reel in big fish. for the money, i prefer the kastkings. just a bit better features at the same pricepoint as other reels, which was their goal all along. i put a kastking royal legend handle on my bmax3 and now love it.
