Lowrance Nautic Insight Pro vs. Insight Genesis for 1 yr

Hi,

my Lowrance Chirp-5 came with an option to get either one - Nautic Insight Pro vs. Insight Genesis for 1 yr. (also Lake, but I'm mostly fishing salt). Which one should I get?

In particular, I would think that if kayaking and small boat community were active on Insight Genesis quality of maps, for particular region, would be better. Of course, I don't know how useful it is, and mostly speculate. And I don't like subscription services in first place.

Is anybody using Insight Genesis?

Thanks!
Sebastian
