I think I'd make the tape angle the same. That will be the most noticeable feature.l
Take into account the dimensions of the table as well as the height. I look for a balance between the legs and the width of the apron. Rather than trying to match the size of the leg at the top, or the taper angle, consider the proportions of the pieces. If you're going to match anything it should be the ratio of the leg tops to the dimensions of the table. As far as taper goes, tapering down to a foot that's roughly 5/8 (0.625) the width of the top is good. With that, you have the golden ratio between the foot and the top since the inverse of 0.625 is 1.60. For a lighter look, you can go a little smaller at the foot, but I wouldn't go too far past 5/8.theart, If I use the same angle for all how would determine the stretch,/compression? A % of the leg length change?
The side tables leg are 21", the sofa table will be 29" and the coffee table 16"
