Since I already timed the other replacement options, here is that one as
well (again, on qt6-6.8.3-x86_64-2_SBo.tgz, where    find . | wc -l
outputs 18282, which is a lot of files and directories).

$ time find .  ! -type l -a \( -perm /111 -a ! -perm 755 -a -exec chmod -f
755 {} + \) -o \( ! -perm /111 -a ! -perm 644 -a -exec chmod -f 644 {} + \)
0.03s user 0.06s system 99% cpu 0.086 total

$ time find .  ! -type l -a \( -perm /111 -a -exec chmod -f 755 {} + \) -o
\( ! -perm /111 -a -exec chmod -f 644 {} + \)
0.07s user 0.22s system 99% cpu 0.285 total

$ time chmod -R u+w,go-w,a+rX-st .    
0.03s user 0.21s system 99% cpu 0.244 total

Certainly the one with ! -perm is the fastest.  Whether brevity is worth
two tenths of a second or not is probably a personal opinion.

Cheers.
