I never get nominated for any of these, so I'm going to nominate a few of my own answers that I think are rather good.
First, I'd like to nominate my self answered question "Does the general public know who superheroes really are in the Marvel Cinematic Universe?". I put a lot of effort into it and I'm happy to say it was received well.
Second, I'd like to nominate my answer to the question "Why aren't the people responsible for creating Ultron arrested at the end of Avengers: Age of Ultron?". This leans heavily on my knowledge of what (broadly speaking) will be happening next in the Marvel Cinematic Universe, as well as some (solid and evidence based) speculation about the details of Captain America: Civil War.
And finally, I feel that my answer to the question "Are there any rules/guidelines regarding Spider-Man's appearance?" never got as much attention as it deserved - it's an interesting (and topical) question that, although potentially looking primarily opinion-based, actually had a definitive answer.
I'd also like to mention "Elvish tattoo - can it be translated into English?" as a great example of why I love this community.
