"better" is the one that has the details you want, how you want it, where you want it.
The maps for Lakemaster that are "Lakemaster High Definition Survey" are very good. The other two types--- not so much. You can download the lake lists on the Humminbird Lakemaster website.
You can view the current Navionics maps on their website's Web App.
Check your waters of interest to see which has what you want.
