A, why wouldn't you, if you know one end of a spanner from the other? Can't remember if I've ever even seen a cartridge bearing hub with adjustable preload and angular contact. They often have crap sealing too.
ii) Shimano are the only ones aside from cheap copies like Alex and Joytech who make proper freehubs which employ the cassette body as a stressed member to put the drive side axle bearing where it belongs.
3, Shimano is like Giant or Toyota; a huge company with engineering resources to burn. They invented almost every major improvement to road bikes in the last forty years, and continue to kick arse.
