D, there are a heck of a lot of different BW LSD centres available, and a heck of a lot of different ways to set them up.
I don't really understand what "pretty crap and clunky" means in any case, given that as far as I know all those LSD's you mentioned are pretty similar in basic design.
Certainly all the Silhouette's I've been in haven't been particularly clunky or noisey in their LSD action. They can be prone to "single spinning" when they are up in the high mileages, but a well rebuilt, shimmed, sprung etc centre should be quite good.
Just taking a 15+ year old skyline diff, shortening it and jamming it in the car will produce just as crap a result as any unrebuilt 15+ year old diff will. Bottom line? if you've driven crappy BW skyline diffs, its most likely either age or poor setup causing the problems.
The Skyline diffs can be clunky or whiney (whether open or LSD), but they can be set up properly to eliminate these problems -and the problems seem confined mainly to the original car - most often due to the pinion carrier bearing wearing and allowing the pinion to ride up and down on the crown wheel, and harmonics in the 3.7:1 and 3.889:1 ratio CWP sets. Easily fixed though.
There are also NUMEROUS aftermarket options for the BW centre, from the 4WD systems mechanical locker, Detroit TruTrac, through to KAAZ aftermarket Torsen centres.
In any case, you get the correct stud pattern and a housing thats a heck of a lot lighter than a Mazda commercial or Hilux diff.
