Answer 1

Chaim's answer to Why was the second Beit HaMikdash destroyed? is impressively comprehensive. It has sources, quotations, translations and summaries from a wide variety of rabbinic literature.

Answer 2

Oliver's answer regarding the possible halakhic issues involved in attending an intermarriage. It is quite comprehensive; indeed the first answer that is comprehensive to an important question asked almost 6 years ago and has had five other answers.

Answer 3

DoubleAA's answer to Who inherits if a man and wife die together? not only answered the question but taught and demonstrated a method to answer "what's the halacha?" questions that arise from talmud study. Not only did I get my answer, but I got tools I and others can apply to future questions.

Answer 4

DonielF's answer to Why are some dates off by one day?. It took a challenging question, worked on the math behind it, and showing how the mistakes made along the way actually helped to answer the question.

Answer 5

Micha Berger's answer to Is there any halachik basis for using "the big two" (shabbat and kosher) as a criteria for frumkeit? addresses the question directly and compellingly by clearly laying out authoritative sources. It also includes worthwhile bonus material that complicates the message in the main answer with equally-authoritative sources. Finally, it sets an example for care for intellectual honesty, in that it acknowledges which aspect of the question it's not addressing and why, it provides an important Halachic caveat in the main answer, and it makes a clear distinction between the main answer and the bonus material, while explaining how the latter complements the former.

Answer 6

TrustMeI'mARabbi's answer to Rebbe Nachman on Connecting to Tzaddikim and Teffilah. While the language of the Likutei Moharan initially did not sit well when first reading (as written in the question),the short and simple insight of Noam Elimelech cited will likely serve to be helpful for those foreign to such a concept enabling them to understand the idea in a reasonable, effective manner.
