I am convinced that Lispworks is a great product. From what I can see it comes with a nice IDE and some nice libraries. I would have loved to give it a try, but unfortunately I was never able to do do so. And that is where the critique of the licensing scheme comes from. I am sure there are quite a few professionals for whom Lispworks has great value and the license costs are just a non-issue. But despite being a professional Lisp programmer for more than 15 years, I never came close to licensing Lispworks. Nor in the 20 years of being a Lisp enthusiast.
As an enthusiast, I would be happy to spend a few hundred € for private usage, but not thousands. I would like to be able to really evaluate the product before spending a significant amount of money on it, but with the limits of the personal edition, it immediately quit on the first attempt of starting my back-then tiny hobby project.
Don't get me wrong, a company has the right to select the business model which fits them best and I might not be their intended audience. But that is why I never bought from them and as I never used the product didn't really put under strong consideration when choosing a Lisp implementation for commercial work.
On the other side, with SBCL I have a really strong Lisp implementation. The compiler is likely to produce better code and it is readily available. Slime might lack the fanciness of a standalone IDE, but as a longtime Emacs user, that might actually be an advantage.
