I've owned both, plus Insite Heathens.
They are all really effective at reducing recoil, but get separated by small details.
I dislike the fact that a wrench is required with the APA LB. If it goes loose and you don't have a wrench on you, tough luck. Mine liked to go loose all the time as well. Sucked when it happened in the middle of a stage.
The Area 419 doesn't require a wrench, but I've had issues with that lock nut collar getting carbon locked. I believe mine got locked up tighter then a nuns you know what in less then 100 rounds. My friends had issues with them carbon locking as well, they've since moved on to other brakes. The brake ports are really sharp (seems like unfinished/unrefined machining to me). If your collar is carbon locked, don't try and get it unstuck with your bare hands - may as well run your hands up and down a cheese grater.
I've really come to like the Insite Heathen brakes. Not on your list, but I believe it's a more refined option then the other two. Doesn't require a wrench to tighten and it doesn't have a tendency to walk itself loose. They don't get carbon locked, not after thousands of rounds. The ports have beveled edges and won't slice your hands open. Aesthetically the most pleasing. The new design with replaceable/changeable bore sizes is a neat touch.
Overall, they all do a great job mitigating recoil. It's the smaller details that really start to separate the different brakes out there in my mind.
