Both the MAE quests and Fiasco are great for overall enemy count, but MAE covers all areas and Fiasco misses a few. I also liked having consistent boss fights. Don't get me wrong, I probably did 80 Fiasco runs too, but this HBR seemed too uber to pass up. Ironically, I found my Pwand during Fiasco xD But several other ubers dropped for others in MAE runs in which I was contributing significantly to the HBR, so I'm glad I helped (ie. Jafet's Heaven Punisher and Cam's beautiful Yunchang).
