Beyerdynamic DT880 vs T90 which to choose?

[TJ Max]

Currently I own a pair of Sennhieser HD558, I'm looking to upgrade from them. I've considered the HD598 and HD600s, but I'd really like  to try a different sound signiture so I'm looking at the Beyerdynamics.
I'm split between the DT880 and the T90 250 ohm versions, which both "look" amazing, but I was wondering which was the overall best? or how do they compare? In terms of Sound and Comfort. I primarily listen to Jazz, Classical, some Jazz/Rock fusion and a few dippings into some new age/electronica like Tagernine Dream.

I have not heard the DT880,
 
but I have the T90's and Sennheiser HD650's
 
The T-90 is a more resolving and coherent sound than the HD650's for me....
 
both sound outstanding with my CSP2 tube amp and Burson Soloist SL
 
the T90 is more expensive, than the DT880, and probably rightfully so....the new Tesla driver is something special
