geography vs economics a level which one is easier???

so, i have to choose my final a level choices by monday and im torn between economics and geography as i love them both equally and perform relatively similarly ( A* in econ and an 8 in geography) . But as i want to do 4 subjects Maths chem physics and geo/ econ i want to know which one is generally easier at a level.. the boards are edexcel for both
im doing 4 cos i really like the sciences as well as social sciences/ humanities such as econ and geo.
