I tried program in "show straight line between points mode" and came out within program resolution of what I got on same course using GE. It does have the advantage (for me) that I can see the plot points. If you have the wrong video card (like me), GE does not show the plot points: OpenGL vs Direct X mode business.
Unless there is a control I missed, resolution is limited to 10 m. I expect to be within 10' on a 5k.
The elevation profile is better than anything else I have seen anywhere. Nice smooth lines like it is going to feel in the real world. You can measure in km for better resolution and then toggle to feet and the Ele Pro comes out in feet. Like GE, it lets you to move the cursor along the elevation profile to locate mile or km marks on the course.
I tried the sharing and saving features and they worked quite well. Dealing with non-techie race directors this is a big plus while the course is being designed. GE's kmz files required the user to have GE installed and most of these folks do not. I end up pasting a screenshot into Paint and marking it and then sending a jpg.
Because of my need for precision though, I will stick with GE.
