depends, my ST1080 are described here rather nice:
http://www.mtbs3d.com/phpbb/viewtopic.php?f=121&t=15100would guess the sony morpheus in beetween the hmz t3 and the st1080, with all negative features you can find in the above forum the st1080 had because of its LCDs vs the hmz(oled), just replace now hmz tx with the rift and the st1080 with the morpheus and remove 1 display, as the morpheus doesn't have 1 1080p display per eye, and don't forget that the rift is a lot better than the hmz's.
I am going for the rift dk2 currently, because of the bigger screens and fov, the st1080 were nice, as i got if for around half the price because of preorder and euro/dollar exchange rate. But it was "just" a big personal video wall in front of you, because you saw this big black/dark cave and the big screen than in it.
I had in the 1 1/2 year of use, no problems with the screen door(ok, its on a very different level than the morpheus in terms of pixels), only with reading text(sometimes), and things that come when you play in 1080p 3D top bottom(1920x2160) at 30 hz some games like arma2 or dayz(also was using TrackIR5:
