What's the best sector to work?

[xfive4x]

I am currently going through the app process and hoping to make it in the October academy. My question is, which sector gets the best calls? My dad, who works 1, has told me to avoid 2, and try for 1 or 3. Any suggestions?

All the sectors get the same kind of calls. 2 & 4 generally have a higher call volume than 1 & 3.

Personally, I like 1.
