Ok, first tests: my Solidoodle 2.
Object: Shy-light by virtox @ 60%
General settings:
Layer Height: 0.2
Infill: 10%
Perimeters:2
Both prints were run by Octoprint. This means the slicers did their job and I exported the g-code wireless to the onboard raspberry pi. Octoprint only starts the print timer once the bed and extruder are warmed up.
Slic3r
Slicing time: 5 minutes 34 seconds
g-code file size: 9,962 kb
Printing time: 02:13:21
My normal profile with 0.2 layer height and sparse infill. This print shows a problem I quite often have where one side of the print is better quality than the other. Note in the first photo the concave band in the first 10mm from the glass. This is constant across many of my prints. Later in the print the right hand side lifted which has contributed to some misshapen parts. This can be seen in the centre vertical part in the first image, where the edge is wonky.
Simplify3D
Slicing time: about 10 seconds
g-code file size: 7,328 kb
Printing time: 02:17:20
I used their default profile except changing nozzle to 0.4 (E3D extruder) and setting the general parameters above. I also tweaked the start and end g-code a bit to try and make it like my Slic3r one. Simplify3D supports [variables] here but there are not as many as Slic3r and ultimately it seems like there is less control for this section. Most of the other settings you can tweak seem similar in complexity to slic3r.
I did spray a touch of hairspray before this one which helped sticking. As a result the right hand side is smoother as it curves up. The overall quality is very similar. Both have some moire pattern in the same place where each layer started. THe inside of the Simplify3D one is much rougher, however.
