What is the best map chip for the Lowrance Hook 5

[bearlake16]

I got the hook 5 in July and just bought the ice transducer and installed on my ATV for ice season. There are a few choices to add more  information with lake maps not sure which is the best Navonics or Fishing hotspots I fish the Midwest most and a few trips to Canada. There are a couple other options I'm not familiar with like a blank chip. What's the best way to go?  Suggestions?
