Both are very good speakers. Here is how they differ.
The Parsifal is very refined and relaxed. Great imaging and very engaging. Dynamics are very good, but not great. Very forgiving to bad recordings, so very easy to listen to.
The IQ is very open and detailed, especially the midrange. It will play louder than the Parsifal and is more dynamic. It also pulls you into the music, but in a different way. It's a "sit up and take notice" kind of sound. Not as kind to bad recordings.
So two different approaches to music reproduction. Only the listener can decide which is best for them.
