Interesting stuff! What you need to be careful about when comparing different foils is to ensure you compare at the same angle-of-attack (AoA). Especially the latter foil has a high "intrinsic" AoA. The best way to do it is running simulations that span a range of AoA, calculating lift and drag for each one, and setting the reference for each foil at the zero lift AoA. Then you can do a fair comparison.
