I wouldn't say it's preferred, also because being LATM a bitstream
syntax brain-farted to carry multiple streams it doesn't make the 
slighest sense in mpeg-ts.
It's one more of the possible syntaxes allowed to carry AAC, and
the worst of all if you ask me, but still it's used in Norway and New
Zealand.
