The Lock Picking Lawyer makes entertaining videos. (Fun fact 1: Harry Houdini picked locks as part of his Vaudeville act 100 years ago.) Number of bicycles the Lock Picking Lawyer has stolen off the street in his videos: 0.

For some 35+ years I used my 1977 Citadel u-lock. Yeah, I used it in places where other bikes were stolen. My bike was never nicked. I used good locking technique, and there were always nicer bikes around locked with little cables.
I can't speak to your locking environment and I don't know your locking technique, but your 2007 OnGuard Brute is still a fine bike lock.
Fun fact 2: the majority of America's vending machines and laundromats have tubular locks.
