Seconded on Simplify3D. It has configurations for many different printers built in, and it’s not hard to configure for one that’s not. Excellent ability to place and adjust supports, and they do indeed usually just fall away. And, it’s a great slicer.
In Cura, go to the top bar - Click expert, Open expert settings. On the right hand side under supports you can change your supports from grid to LINES which always remove easier. Then look down to distance z and bump it up to .2 but be aware this may affect your clean edges a bit. If using a raft, you can increase the air gap there as well. It is clearly labeled as Air Gap under the Raft settings. If struggling with raft removal you can also try turning your fan on earlier (say at layer 2 or so).
Here is a great reference for quick trouble shooting using Cura. Some of it is Ultimaker specific but still may be useful.
Also, I am really impressed with the helpful tips from Matter Hackers. I LOVE using Matter Control (under configuration you can choose to use their slicing engine, Cura, or Slic3r so that’s pretty cool). Also, Lars is really knowledgable, responsive and helpful.

I hear really great things about Simplify 3D but I like to go the freeware or open source route since mostly I am teaching others and prefer to make things as accessible as possible. Let me know if that is helpful or if you have other questions.
I use Simplify3d and it allows me to design the way the support material will be set. Still some times you will get designs that not even the best of the programs will prevent having to do some serious cleanups. For these occasions I have different types of blades, sandpaper and a little butane torch (be careful using it).
