I found the first solution easier to understand, but I have this infuriating (even to myself) obsession with ternary operators that could introducing some bias.
One of my pet hates is when the c# style is for opening braces on a new line, making if/then/else statements much longer than they need to be, so people try to cram as much into a single ternary as possible.
Although given that there are only two properties to process, the gopher-style assignment code preferred by the author would suffice anyway.
