i know your comment is 4 months old now, hopefully this will still be relevant to you:
I recently upgraded from Repetier-Host, Cura, and Slic3r, to S3D. The difference is immediately noticeable. slicing times are wicked fast, surface finish of printed parts is much nicer, the support material is an absolute dream, it works. it ACTUALLY WORKS!
In other news, i swear my printer is actually quieter now, at the same speeds, i experience zero oozing, and ive never had a print failure at all. I bought it from PrintedSolid, who pledged to give me any support i needed, but i’ve not needed any.
