I have checked it out and I don't recommend it to others.

Racket is not Scheme anymore (it can't use SLIB, which relies on
common Scheme facilities). Racket is a language and an environment on
their own. For instance: debugging facilities are hidden into its IDE,
therefore you'll have to leave your debugging environment of choice.
Yes, you can run a REpL outside of its IDE, but you can't do much more
than that.
