I have both a chartplotter and laptop with charts.
The chartplotter is better, if you can afford it its worth the extra cost. The main differences are
1. Stability. the chartplotter works 100% of the time within a few seconds of turning it on. The laptop is slower to start. It works most of the time, but dragging in the middle of the night you do not have time to fool around sorting out problems with windows.
2 Waterproof. The place for a chartplotter is at the helm.
3 Daylight viewing. even at the chart table sunlight can make the laptop screen hard to use.
4 Radar overlay. shows errors in the chart. Invaluable. (possible with a PC system but difficult and even more tempramental.
