a better question might be, "why not brunswick ?"
if you go to this website long enough you'll see many people post remarks like coverstock death, balls that crack, balls that don't hook any more, etc. i've never had any of these problems with brunswick equipment. a little common sense like cleaing your equipment, oil removal via the revivor and/or rejuvenator, and upkeep on coverstock surfaces.
you've stated you haven't used your brunswick equipment that long. it takes time to get used to a useable and readable ball reaction. you may also have to experiment with surface changes on your equipment. i almost never use my equipment in "box condition ".
