Just a personal preference, but I still prefer the view from the SE and EII better than any roof out there, and I must have tried them all by now, including SV's. Most recently I owned an SLC HD 8x42 for a few months so got to know it quite well, and a stunning bin it was ( apart from the awful focuser) but still it didn't wow me quite as much as the SE.
I guess my eyes just settle more easily into the porro view. Apart from the obvious 3D advantage I seem to perceive a sharper, more transparent, more clearly defined image with the SE's , though I doubt they are really any sharper than the SLC HD or SV.
So, from a purely optical point of view, for me, the SE's are still unsurpassed.
