felt my anger ebb away / ebbing away

[Mnemon]

Hi,

A - I felt my anger ebb away and a feeling of shame came over me.
B - I felt my anger ebbing away and a feeling of shame came over me.

Do they both sound idiomatic to you? If yes, could you please explain the difference?

 

[tedmc]

Yes, the infinitive and continuous form of the verb makes no difference to me.
