Typeface Comparison 6

I am comparing Kabel Book and Futura typefaces. 

• Both typefaces focus on using circular shapes in their letterforms-- for Futura it is in its bowls, and in Kabel it is in both its bowls and other aspects of its letters such as two story A's and G's
• The set width in Kabel Book seems just slightly larger than in Futura.
• Both are san serifs and have no visible contrast in the modulation of the letterforms
• The weight is heavier in Futura than in Kabel Book.
