As far as which card may be better, you would have to look up the directory of what lakes are covered on each card and to what extent they are detailed.

When you insert a mapping card into a Lowrance head unit, it can only be read by that unit. This data cannot be shared with additional units or copied to other cards. This is the way the mapping companies make the card. It has nothing with any marine electronics inability to transfer or share this proprietary data.
