I have always used Garmin. I have a 7" echo chirp Garmin on my boat right now. It has the blue charts on it and then using my computer inputting all fishing spots and reefs that I use, i have never had an issue with my Garmins and have used them for 20 years. Easy to see in the sun, easy to use. And easy to start up and is works great. I always like the interface with Garmin. I don't really have to read a manual to make it do what I want and while on the water I really don't want to fight with the chart plotter or fish finder. With fish finder I fish shallow water and felt the Garmin gave great detail in shallows. It has dual beam width and down scan with are very clear. I can see pretty much everything. Even my lure.
You really need to look at what kind of water you are going to fish. Here in Texas Lowrance, Garmin and Hummingbird are Garmin for fishing and bottom detail. The other brands are more pricy and are better for deeper water and navigation.

Bottom line, all are good and all work well, they just cater to different styles of waters and types of fishing.
