I know that "That's good" can be either:

Tá sé sin go maith or Is maith sin

But would "That's nice" be either:

Tá sé sin go deas or Is deas sin?

In either case, would the copular forms be more acceptable or more frequently used?

(totally equivalent would be sin in both cases or sé sin/é sin )




Is maith sin is frequently used, is deas sin isn't.
