I have five builders. I'll go to TH 10 in about a month.
1 Infernos
2 New buildings
3 Lab
4 Spell Factory
5 Camps
In higher leagues infernos kill my troops most so that's obvious why they are first.
New buildings including resources to fill out my base so I don't have to keep modifying my layout.
The rest is pretty obvious.
Lab is third, I use LavaLoonion mostly so the lab isn't super critical but I want to keep it busy as possible.
