Creative vs Straightforward essays?

Should I follow a straightforward approach in my essays, just listing what I want to say, or is it better to follow a stylistic approach?

I just got deferred so my advice probably isn’t as valuable as that of an adMIT, but I went with a combination of both. I tried to be funny and lighthearted in most of my essays but really serious in others.

Neither extreme.

I was admitted, and my essays were written in varying styles. Don’t overthink it, just be honest and open in your essays.
