Logitech Z-5500 vs Z-906

Hey guys,
So basically I own some Z-5500’s and I love em to bits, but the sub blew and they are still under warranty so I am sending them back to Logitech to them replaced, but they have given me the option of either getting some more Z-5500s or the Z-906’s and I’m not sure what to go for.
I trust this forum hugely, so any help would be much appreciated

I’ve got a set of the Z-5500’s connected to this pc (they are about 6 years old, got them free from Dell) best set of pc speakers I have ever had. I haven’t seen or heard the Z906’s so can’t really put an opinion here.
