I think the main disadvantages of adopting PAL in South America were economical, that it made it less likely that a color TV manufacturing plant could be established there without government support either directly to the manufacturer or by high tariffs on imports. Plus, the production and stocking of special models for those countries may have raised retail prices.

Technically, once equipment became transistorized and stable, the only advantage of PAL transmission I can think of was the reduction of wrong hues in ghost images.

There may have been an improvement in color accuracy (as there was in Europe) if the cameras were matrixed to the EBU phosphor standards and receivers used unmodified R-Y and B-Y axes. In the US, color matrixing was a sort of wild west situation in which CRTs did not use NTSC phosphors, but cameras (at least the early ones) were designed for them, while different TV makers did various non-ideal modifications to the chroma decoders to compensate approximately.
