I sort of had to figure out your definitions there. Unfortunately, I have to disagree, any television system can develop these faults because they're frequently due to limitations in the broadcast chain or problems within the receiving set itself. NTSC does not inherently have any more difficulty than any other system with saturation problems.

In fact NTSC has superior transmission characteristics for long distance cable/microwave transmission than either SECAM or PAL.

NTSC has no problems decoding to RGB. There has been over the years some disagreement on implementations of color decoding in NTSC. 3 different revisions if memory serves. The latest one was in the 80's and dealt with modern phosphors on TV sets. Current NTSC broadcast chains should decode correctly for modern TV's.

It might be a true statement, although I haven't read anything that would confirm or deny it. NTSC does tend to be easier to impliment in closed circuit situations. The signaling is simpler, and some of the timings less critical. Since long distance cables, either copper or fiber optic, use FM modulation to transport the signal its feasible that NTSC might be easier to deal with. And using the FM modulation scheme means there are no phase issues, which is the real reason why PAL was developed to begin with. Still I haven't read anything definitive on if that's true or not.
