The EX1000, IMO has much better timbre, mids (more forward), bass quality (especially sub bass), wider and deeper sound stage, more realistic sounding instruments.
The TF10 has greater quantity mid bass, more dynamic (energy). The UE has a V shaped sound stage and the Sony is arguably mid forward and definitely a brighter phone. The EX1000 is more comfortable. I am sure I am missing some other positive attributes of the EX1000.
I prefer to listen to the EX1000 and to me, is the much better phone.
