I personally loved DT990 600 ohm for acoustic and metal music, soundtracks, movies and games. The difference as Mal stated is very miniscule. I currently have both the 320hm and 250ohm ATM, ad the 600ohm will be here in two days. I have already owned the 600ohm twice, with better equipment (I stepped down to a simpler setup).

I have been using my Astro A50 Gen 4 for a while now and feel like I want another pair. Decided to go with the DT-990 (250) because of the great reviews and like the Astro eq command center.
