I recommend using Bubble.io for most web applications, including SaaS platforms, marketplaces, e-commerce, social media platforms and much more. While Bubble.io does a lot well, it could do a better job at processing/creating data faster. So if you have a heavily intensive application where you need to create and pass around millions of rows of data in short amounts of time, it might be worth looking at other backend systems to use.
C1 is great for creating custom reports. We have client apps where we've created some fairly complicated reports such as invoices and real estate inspections. We also use the True DBGrid in many of our apps since it is so customizable. Its grouping and filtering features are very nice and can provide summary counts and totals at the bottom or right side of the grid that are very handy.
The True DBGrid control is nice for showing parent/child relationships and being able to drill down and show the child data. It also is nice for showing summary totals.
The report engine is great for building custom reports for Win Forms or web apps. It can do everything that Crystal Reports can do.
They have a good selection of controls that can do just about anything you can imagine.
We have been in business since 1992, so we have used many different products over the years. The two other products we've primary used that are similar to ComponentOne, are Infragistics and Crystal Reports. Infragistics has a vast array of controls similar to ComponentOne. We use both to be honest and I'm not sure which one I would pick over the other. I guess that would depend on what you're trying to accomplish and if one had some control or capability that the other didn't. ComponentOne does have the reporting capabilities, where Infragistics does not.
ComponentOne allows us to add additional features to our apps that wouldn't be found in apps written with just Visual Studio itself. That allows our clients to get more creative in their requirements, which in turn, means more work and billable hours for us!
Our apps appear more professional when using ComponentOne which helps us get projects for new clients.
ComponentOne also helps us to save clients some money since we are not having to develop things that it can do from scratch.
