I had a look at some of these projects, and my impression is quite a bit less enthusiastic.
A lot of it feels rushed rather than finished. Once you actually start using the applications, you run into bugs and inconsistencies pretty quickly, and some of those look less like small polish issues and more like structural problems underneath.
I also wonder whether spreading the effort across so many Adobe-style clones at once is part of the problem. If the same energy had gone into one or two applications first, the result might have been much stronger and easier to stabilize.
