Before I saw the light and switched to Android, my primary use for Siri was asking her ridiculous questions like, "Are you single?" And "What's your favorite color?" I still can do that with Google Assistant, but when I ask intelligent questions like, "Who played Scar in The Lion King?" I get an actual answer instead of search results.
I usw Google for basically everything. Email, photo storage, contacts, calendar, GPS, Apps...everything except what it was originally intended for: searching. I prefer Bing, except for image searches.
