For me the best code is the easiest to read. Something like a few lines to define variables, a few lines to assign values to them, and then code, one action per line, on each variable. I prefer that to “one line that does it all”.

I believe that if the code is very simple and easy to read for me as a human, it will also be for the compiler.

I try as best as I can to write very simple (almost stupid, “in steps”) code, and then trace it even when it works to see what is happening (and in second run, change values on the run to make it fail).
