The thing is that the Adobe Standard profile, is a profile just like all the other "Camera" options, and specific to each camera body you are using.
The difference is that the Adobe Standard profile is designed to give a conversion that is approximatly consistent across all bodies from all manufacturers. So if you have both a Canon and a Nikon body, the Adobe Standard conversion should look about the same from each body.
For the Canon bodies, and I assume other makes where manufacturers offer them, the Camera profiles are designed to match the same named profile as offered by the cameras JPEG processing engine, or OEM RAW converter.
I used to use Camera Landscape a lot, but recently I have also been using Adobe Standard quite a bit. Personally unless you are doing very critical colour matching, where you should be profiling your own camera, profile choice is really an artistic choice, so try out some different options.
One thing to remember though is changing the profile will often require significant other changes to all the basic tab controls, including the WB, for best results. One reason I started using Adobe Standard more was because I was finding that the Camera profiles all tended to push the reds up too much so that they would clip. Adobe Standard is much nicer to those red hues. At least for my camera, and shooting style.
