Don't conflate the concept with the syntax. The fact that Python now
has "the walrus operator" says that assignment expressions are useful.
The issue with the C version is that the assignment and comparison
operators look too much alike and using the wrong one can cause *silent*
catastrophes (although modern C compilers can and do emit appropriate
warnings or errors, if you ask them nicely).

Simplicity of syntax. Very few languages have a simpler syntax than
Lisp (Ook, et al, notwithstanding).
