Which Navionics Version Do You Suggest

So here's the scoop. I bought a lakemaster plus card for my humminbirds a couple weeks ago. I plugged it in yesterday to find out that is has only one of the lakes I'm scheduled to fish at this season. I talked to my old teammate and he told me he went with navionics because they have a lot more of our local lakes. I had always thought it was just a thing where lowrance guys like navionics and bird guys like lakemaster. So now I am sending back the lakemaster card and plan to buy a navionics card. Which version should I get? There are like 3 or 4 of them. Is hotmaps platinum worth it? Or should I just get one of the other versions?
