Over the years, been using chart plotters since 1997, I have come across many errors and omitted pieces of data from the NOAA cartography. This is why I still carry paper and do my best to mix that and my plotters information with "local knowledge". When cruising my home waters paper only comes out in thick fog but it is still always on-board.
While errors can happen anywhere, errors in NOAA electronic charts (vector or raster) are relatively rare and, more importantly, if there is an error in NOAA electronic chart - you can expect the same error in current paper chart.
At this point NOAA paper charts are generated from the same electronic data as those you download and use with navigation software. So while there is a benefit of redundancy with paper charts, there is no benefit of "better information" anymore.
