Master lock company is in Milwaukee, or use to be, now they are probably in china. American lock company I believe is in illionis, though its a long time since ive read their literature. the american lock is more secure I would believe, the lock bodies can come in harden steel, or aluminum, and some of them have genuinely bolt cutter resistant shackles, the ones with the thick shackles, the others, seem to have shackles that will cut, this could be for those who want the lock to indicate when its been tampered with, but still cuttable if the owners lose the key.
