Is there any difference between the 24k equivalent topo maps on the Topo 24k series vs the Huntview plus (SD Card Version)? I am aware of the advertised advantages to Huntview (birdseye imagery, land ownership, etc.) - but would like to know if the actual map quality differs, or if the Huntview series includes more trails, additional user data such as unofficial trails, campsites, etc. My application is backpacking, and my primary area of interest is Idaho. If there is little or no difference - I will select the Topo 24k option (since it covers more states). If there is additional local detail - then the Huntview option may be better.
