The other nice thing is the warnings whenever you come close to a bridge or overhead cable to verify height. It's nice to be alerted to this warning way before you spend too much time figuring out a proper path.
I use the auto route occasionally in Navionics one my Raymarine MFD and I Pad but mainly lay my route manually due to the closeness it could get to shoals sometimes.

I personally like the Navionics as it shows great current vectors as well as peak and lack of current vectors according to time. Invaluable in sailing in areas with reversing current . With that you can adjust the average speed of the boat when plotting the route.

A course into the current will have a different end time than one with all current with you or half time with you. Navionics can show that to you.

The other point is that the course does not equal anything but a straight rumb line, but wind direction can / will change that. Again something you can adjust for on a manual mode.
