I have had the “pleasure” of experiencing a lot of these solutions over the years. And I guess an important thing to keep in mind is that these tools probably isn’t that fair to compare with the kind of development I typically do. Either because of staffing, money or other reasons.

But from a user side of things I always find them incredibly slow with a user experience that leaves A LOT to be desired. While on the development side it is also slow to set them up, with surprising little of the easy duplication and re-use you see in conventional software development and also the apps are very slow and cumbersome in themselves.

Again, I’m most likely not the target audience.
