I don't have trouble with the BLD function for the most part, it's just very context dependent. Since it's (only) reactive that means you have to first lose traction before it will begin to operate and when it does it's a little bit jerky if you're in a precarious position.
Years ago a Jeep drivetrain engineer Q&A revealed the insight that they aim to provide the widest envelope of capability to the largest percent of users, in other words they want to give your granny all the features in a way that works for her & not necessarily offer features that require a knowledgeable user to employ them properly.
It's been my experience with these vehicles, both my Ram and my pretend Jeep that the best approach is to drive a bit like I might if I didn't have decades of outdoorsmanship under my belt. Pretty often just committing to a line and maintaining a steady speed (not lifting my right foot or doing my own braking at the critical moment) will let the system work as designed and it can be pretty effective.
My pretend jeep has open diffs and BLD, and my 2015 ram has the OEM non-preload, clutch LSD in addition to BLD, obviously the chassis and suspension are different enough that the same spots on the same routes don't present the same challenge but when I get them into equivalent situations it's still very obvious when the LSD has become locked because as long as constant torque remains on it tends to remain tight and there's no further slip or intervention from the BLD. That's extremely useful when trying to ooze up a ledge without putting any shock loads into the axle shafts.
On the other hand my pretend jeep has no low range transfer case so the maximum torque it can deliver to the wheels is close to nothing and when BLD kicks in the loaded wheel gets half of nothing. That means most of the time when I have to climb a set of moguls the only option is to use speed and hope for the best because if I depend on BLD to stop the unloaded wheel I'm going nowhere and cooking the transmission.
I could imagine something like that being a problem in a heavily loaded Ram on 37's and real nasty terrain.
A clutch LSD with preload is a little bit proactive (and more rapidly reactive) but they wear out faster, a helical LSD is always proactive but can never approach a full lock, which matters without BLD from my experience. I've never driven a vehicle with both helical LSD and BLD, on paper it sounds like an excellent combo.
So far based on my use of the Ram truck I have not been disappointed by the BLD & no-preload factory LSD. I could imagine it being frustrating in any kind of racing or extreme terrain, or for any experienced outdoorsman who'd rather not unlearn the careful techniques they spent decades learning.

not sure if she's taking one for the team or doesn't know what she's getting into. Bahaha
