As David said, The Beast have certain issues, Not being balanced being the biggest issue, The heavy weight amplifies it, I have also seen some that are not True. Many Builder swear by them because they don't break.....But what's the point if it's going to beat the Bushings out.
The Stock Delco Sunshell is Fine for under 350 ft/lbs, It was updated a few times & alot better than they used to be (Softer material to prevent breakage), The stuff you read on the internet is from problems 20 years ago.
The Delco shell has 1 Achilles Heel, The Splines can Strip if to much torque is applied. Or towing heavy through hilly terrain....Constant 2-3, 3-2, 2-3, 3-2 can wear the splines, But other things wear as well under these conditions, The pic is a 3-4 clutch plate from a 4.8L/4L60E truck that tows through Colorado a lot, I rebuilt it about 60,000 miles ago, The Sunshell stripped, But look at the internal tangs on the Clutch plate....Almost worn off!!
Point is the Stock shell will last as long as the rest of the Trans IF not over torqued.
The Sonnax Sunshell is actually a reinforced stock shell, A plate is welded around the splined to stop deformation, The reverse input drive lugs are heat treated. A Torrington bearing is added to keep thrust load off the Reaction Planet Torrington. This is a very nice piece, & if funds allow....Highly recommended.
