Formal:

* Gwych - This is a good general option meaning "excellent" or "wonderful."

* Rhwystredig - This translates more literally as "amazing," and carries a sense of awe or wonder.

Informal:

* Anhygoel - This is often used for something that is unbelievable or incredible.

* Ffantastig - This is a common term for something "fantastic" or "brilliant."
