We used both. As I see it, every solution has this pro and contra.
DevExpress
- Responsible (as in fast) components.
- Conforms to the Microsoft standard.
- Clear code.
- Very good support.
- Expensive.
TMS
- Not as fast (as fast) as DevExpress.
- Looking at the code, cleaning things up doesn't hurt.
- Very good support.
- Inexpensive.
