Part of your decision should be to look at the lakes you fish and who has the best maps for that lake Garmin is limited to what maps you can use. There are some things about the Humminbird that are really nice to have if you ever wanted 360, I Pilot link, I believe the 7 has auto chart live now depth highlight which I use all the time and more just not sure what is all on the 7 since I run the Hbird 1198 and Helix 12 gen1.
