in the lower units its all about the same, as you go up the big difference is in the mapping and charts between lakemaster and navionics. I run 2 highend humminbirds and overall I feel they are the best units, but the 2D sonar in high end goes to lowrance hands down, humminbird leaves something to be desired in their side imaging units, but the side, chart, down is better than lowrance, so it depends on what you want to compromise on. for me I can tell what anything is on 2D sonar even in black+white so everything else matters to me much more. I have seen the garmins and they look very nice and hear good things about them, not sure if you are going above basic and want chartplotting/charts, I think the have lakevu on their units Id take a look at what that gives you. right now w lakemaster and navionics you get good maps of LH, GWL, and Monks, all the rest have not been mapped and they are 3D versions of the state lake maps. Both lowrance and humminbird give you a way to map your own lake chart, but its pricey equipment wise, so you gotta do your homework. humminbird is the only game in town if you run ipilot or ilink, so Im stuck with them I cant fish without my ulterra
