Navionics or lakemaster

Got a new 2020 nitro z18. It came with a helix 9. Never had hummingbird before always lowrance. Which one do you prefer. I'm driving myself crazy searching. I'll be using it in the north east region. Thanks for any info

I originally had the Navionics card for NE lakes. Didn't know when I bought it that there is an annual subscription fee.

Moved to Lakemaster this year. One time charge. 

YMMV
