Larue is no where near as rugged as Alamo. Never had bobro but I used to run larue until a friend at a course showed up with Alamo dloc and was very impressed. You have 2 small cross slots to lock in the picatinny rail with larue. With Alamo, you have 6!! They run across the entire surface of the picatinny as well. Amount of clamping surface with the larue versus alamo is also a fraction.
6 full locking bars with Alamo versus 2 with larue guarantees better lock up and zero repeat, especially under harsh conditions like dropping your rifle, slamming getting out of vehicle, hitting the deck, etc.
