Honestly I recommend having both ...and here's why ...

There is no possible way for a map card company's survey boat to physically be on every inch of every lake ... This creates "holes" of no data in their end result map product ...

So map card companies "interpolate" data for these "holes" in the product ... This interpolated data can be old Corps charts, leased data from other sources, software designed specifically for interpolating map data based on nearby contours, etc ...

What this means is all map cards (regardless of brand) will have inaccuracies in specific areas ...

If I'm in bay "x" - and the data on map card "L" is incorrect = I will insert map card "N" and check it for accuracy ...

Over time - I have learned which map card I'm going to be using for the area I'm fishing that day ...

Sure it's another $150 expense - but a good investment in my opinion ...
