Side missions scale to your level so a side mission is just as useful at level 1 and level 25. Unlike main mission where you dont get more exp for being over leveled. So if youre efficient you can save the side mission for when you need them late in the game because there are other activities that give you more exp for your level..... ex main missions

The only side mission you want to do ASAP is Dept of Justice....it gives you a magazine mod that gives you 30 more bullets.

Probably the most efficient is Main mission, Control Points, Projects (which can be completed passively), and then side quests for things you actually want.
Great tips here, thanks ChenBop!
