SLHA files and hepmc data available (M. van Beekveld) see below.
For the first two compressed Higgsino samples there is no real sensitivity (what little there is in the missing energy + jets analysis). For the third sample there is a strong exclusion coming from the missing energy + jets. It not obvious to me why the different masses should have such a dramatic impact given the simialr compressed hierarchy.
For the compressed stop and sbottom, the story for all three samples is similar to the first two Higgsino samples, with the 8 TeV data have less sensitivity than the 13TeV.
