I don’t believe so. The compiler condenses it down pretty much the same either way. Just write it whichever way feels most natural to you.

var x = 0;
if (Random.value < .5) {
	x = 1;
}
else {
	x = 2;
}

is slightly slower than

var x = Random.value < .5? 1 : 2;

However, the difference is small enough (a couple %) that you’d only ever consider it a factor if it was looping millions of times in a tight loop, and maybe not even then. So basically what FizixMan said…code readability is more important.
