No question that "bigger is better" when selecting a chartplotter as long as
there is space at the helm.
For someone wanting to use a chartplotter in an enclosed (dry) area who
already owns a laptop, nothing beats the economy of adding a GPS antenna and
loading free or $49 chart/navigation programs. Plus the screen is HUGE. But
sufficient helm space is required.
For complete reliability and permanent mounting a dedicated chartplotter is
the way to go. No viruses from the internet, no hard (mechanical) disc to
fail, better moisture resistance, simpler button controls. More reliable
software.
Another consideration is the number of helm stations requiring plotter
capability and the use of other networked navigation tools, like radar or
depth display equipment.
I have Raymarine, Interphase and Standard Horizon plotters aboard. The
displays have all been just fine, but the logic for use of each is a bit
different, so I'd not likely mix brands again. Unless I practice each year, I
forget how to use the least frequently used ones.
Another consideration, one which I forgot when making my purchase decisions,
is the desireability of having a remote (anchor) alarm capability at your
berth. During a stormy night setting an anchor alarm which can be heard at
your berth is a great safety feature. Alternatively, an intercom from your
helm station to berth can also provide this function.
