Map question for the Garmin gurus

[motomark73]

I have an Echomap UHD 73SV which includes the LakeVu G3. I'm headed to Florida in May (Gulf of Mexico-Sanibel) and want to purchase 2nd set of maps. It appears I have an option for BlueChart G3 or Navionics+ both in the "large- whole country version". The Navionics+ is $199 and G3 BlueChart is $219. It appears Navionics+ also includes all inland waterways (which I already have embedded in device- LakeVu G3). So it would seem the Navionics+ has a ton more data, but I am guessing it must be giving up a bunch of details or views. Anyone done any extensive research into Navionics+ vs BlueChart G3? I'm guessing neither is a loser, just curious if anyone has experience with both. Thanks in advance!

I would be interested in info on this as well.

@motomark73 I don't have experience in both, but I believe G3 is now built with Navionics data, so they should be essentially the same info.

Doesn't the LakeVu G3 cover that area? I took a look online and your included maps might cover the intracoastal? I wasn't sure what my maps covered, so I zoomed around various areas to see what it detailed. Maybe check to see what your included maps actually cover before buying duplicate maps?
