If you have an unparalleled skill set that proves you are an asset, don't leave that on the table. Offer insights as to how grounded and well-rounded you are. The qualifications of the other candidates they're interviewing will remain as much of a mystery to you as how their interview performances compare to yours. Therefore, there's no point in competing with them when you deliver your answer. The only thing you have to go on is your own merits. If your noteworthy merits have contributed to your past employers, sing your own laurels by detailing how. The more tangibles you can deliver, the better.

"I am all about systems implementation. I'm that person who strives to deliver above and beyond quality in my work, then implement procedures that increase quantity without sacrificing quality. So, whenever I finish my onboarding, I get started on analyzing what I've learned and identify methods to improve my workflow and productivity. Once I feel I've done so, I'll share my method with anyone who is interested. In my last job, this led to several improved systems in the entire department, which increased our department's productivity threefold."
