KISSlicer has some nice features:

Easy selection between fast and precise
The printer settings contain one set of parameters for a fast speed and another set for precise operation. Using a slider you can select between those without having to change any of the parameters.

Raft
Select between a raft or a brim and select how much bigger the fast must be than your object.

Support with a 'sheath' given a more stronger support that does not break away during printing. The support also gets more dense when the object is reached (vertically) forming a kind of raft - this gives a higher quality surface.

Prime pillar
Primes the extruder before each layer starts. This is especially useful when using multiple extruders where you want to prime the extruder before printing a layer.

Tool path preview
Very easy to use 2D or 3D toolpath preview.
