For new projects with Kinetis MCU should we use KDS or MCUXpresso

We are using K22DN512xxx5 for this project

For new projects, I recommend to use MCUXpresso IDE. Because this is what will be moved forward, and you get more functionality with it with a newer IDE and toolchain, including SWO and trace features.
