LP Smartside Siding

Regarding the LP Smartside Paneling by Louisiana-Pacific:
I read that several years back, and even fairly recently, there were many lawsuits regarding their T1-11 type of paneling products. Not too sure why, but think it was due to de-laminationg.
Was wondering what the consensus is here regarding their present day products like "LP Smartside" ?
Have they gotten their act together, fully, by now, or is still a good company to avoid ?
BTW: still trying to learn about T1-11, as I have several panels that need replacement.
Anyone happen to know if any mfg. offers this stuff pre-primed ?
Are there different "quality levels" of ?
Any single mfg generally thought of as to offering the best T1-11 ?
Is 303 the same as T1-11 ?
Thanks, Bob
