Peter White says they are basically the same, but Schmidt claim higher Lux measurements and I've seen comments also that Schmidt use a better lens which gets rid of some artifacts in the light. I agree that the Edelux looks nice, but hesitate to part with more than twice the price (~ 60 EUR from Bike-discount for the Cyo Premium, £120+ for the Edelux II) unless there is a noticeable difference in the light quality, spread or brightness.
Also, there is a comment on the Schmidt web site about how the light is asymmetric like a car headlight to reduce dazzle for oncoming drivers, which would mean it would give more light out to the right (for those riding on the right hand side of the road), so make it less suitable if anything for the UK.

The Edelux II has better cooling, the front glass is treated with anti-reflective material for higher light transmission, so it ought to be slightly better than the Cyo Premium. The old Edelux would have roughly 10% higher output over the Cyo. Nice, but probably really hard to notice.
So the Edelux II probably has slightly better output, much better RF shielding so as not to disturb wireless cyclocomputers (not seen the new Premium tested, but even if its RF shielding has improved, it probably isn't a match for the Edelux). Beautiful build quality.
As I understand it, the Edelux II is really watertight. The Cyo Premium has another strategy; it is not completely watertight all around since it allows draining of water ingress or condensation.
The light beam pattern are identical on both the Edelux II and the Cyo Premium. There is nothing asymmetrical about its beam pattern on the lateral plane, and it would be hard to make due to the TA23/StZVO test that defines that the most intensive part of the beam should be in the middle.
(edit: sorry for posting the same pic twice in this thread)
Here is the Edelux II beam pattern as seen on the ground from above. The distance is 50 meters, the intensity is in Lux (log scale).
At 28 meters distance the beam goes below 8 Lux, don't expect much above that distance.
Is the Edelux II worth the extra price? Probably depend on one's cycling budget.
