Second question: They all reward the highest amount of tools of their kind. Ie. There are only two collections (from memory) that offer 5 flying times but the other requires cotton fixer, so Model Town is the most requested. I also think most of the collections that you listed are early quests, and sometimes players don't know they can specifically search/filter their inventory by tools- so they go with the ones they know.
