9" Echomap vs GPSmap for general use and livescope

[txchaser]

I'm assuming that the humminbird livescope is still nowhere near the garmin, if that's not true let me know. 

 

I'm seriously considering livescope+, I've fished with it a few times and it's really interesting. Seems like the Echomap and GPSmap both work fine with it, but the GPSmap is a) significantly more expensive and b) significantly higher resolution. I don't mind the buy once cry once, but 9" is the biggest I can fit, and if there's no practical difference between the two it'd be good to know.

 

Anyone have experience with the difference? Thinking about livescope itself, 2d/si/di differences, mapping differences etc. Any general advice? 

 

Thanks!
