I've always argued for S3D.
On forums, and Facebook groups when people asked why would you bother spending $150 on something that you can get free elsewhere I'd always tell them that it's worth it because S3D just performs better and has better features.
When they came to me and started explaining that all these free slicers now have advanced features that S3D doesn't begin to approach, I explained that S3D probably doesn't need half of them because the results are just so good, and that the user interface is so nice.
But now, this is just a joke. Almost 2 years since the last update came out, and free slicers are lightyears ahead of this.
Sorry S3D, even 6 months ago I'd have probably been prepared to pay a full $150 again for V5 but now, unless you really do do something mindblowing, I'm out. You guys messed up and you messed up big!
