Chartplotter card ???

[JMatlock]

Currently, I have a Navionics+ card, but I need to renew it. Looking at the Navionics Platinum+ or CMaps Reveal. I know both have most of the lakes really well covered in Northern California. My question would be which one has better coverage of the Delta. I like CMaps having the color shading and the Shaded Relief. Not looking for a brand battle, mainly who covers the Delta better or any general pros/cons of each. I have Lowrance HDS Live displays. Thanks.
