Tried Cura and I really like it. Kisslicer next?

As I continue to learn and experiment on this printer I decided that wi would try our Cura. I like it. The final print appeared much nicer than the slicer version! Wasn't too hard to setup. I basically copied the configs sent by Colin. What I didn't like was the support. Granted, my model may not have needed support. It was a hollow cube with square cutouts on each wall about 10mm wide. The cube was 13mm in dimension. The final result was a wire frame of a cube. Instead of making the frame square, slicer put an "overhang" on the model. Basically I thought that it would run support down to the frame on the bottom like Slic3r does but it didn't the holes, instead of being square, are pentagonal. Is this what Cura put in for support?

No pics yet, sorry. Will take some tonight.

Kisslicer however looks to be a bit more intimidating. For example, you don't have a Marlin voice of firmware listed. just...
