Resources get the most XP. Oil and Metal that you get from NPCs and other players and from your plants at your base. Even if you are maxed out on your resources, you can still get XP from loot. If you build up your towers, power plants, and some buildings you will get XP from that as well. Ten Million in resources will bring about 200,000 in XP. This is the amount that you can get off of a lvl 30 NPC Base.
