As far as I can tell, both modes give the same total number of points at max level for a new character (100 for the player and 80 for the squad mates).
It was broken in the original release, so that might be causing some weirdness if you're using an existing save.
I did a test run for the heck of it. I don't have the image from one of the chracter creations, but I finished that one using classic mode starting at lvl 57 (lvl 29 on legendary). After getting to 60, I earned 3 talent point for each of the final three levels. On another creation that I used as an imprt to ME2, it was also on lvl 29/57. There I ran the game out on legendary and got 2 points, one less than running at classic from lvls 58-60. As you can see, when I hit lvl 30, I got just 2 points.
