Arvon- in terms of strict S&S synthesis, the Roland is more powerful (better filters IMHO and many more ways to configure the oscillators using different structures). You must also remember that the Triton's polyphony is halved with a 2 oscillator program bringing it down to 31 voices (unlike Kurzweils which stay the same even with 3 oscillators- that's true polyphony IMHO). The XV's polyphony is cut down to 32 notes with 4 oscillator patches. But I do believe that Korg can be fatter sounds that Roland with just 2 oscillators (that's just IMHO of course!).

With regards to the above post- both these synthes (Triton and XV3080) have their own 'sound'. To me, the Triton also has fantastic EP sounds even the factory ones (just as good as XV's but different!). Strings- Korgs are more realistic and sharper but Roland's are warmer. Both do awesome pads, basses and leads. Electric Guitars- Triton definetly (the best EG sounds of any S&S synthe IMHO) Acoustic Guitars- Roland XV (but Korg's not far behind). Drums- the Triton is much better at the dance/contemporary sounds but the Roland definetly wins out with it's acoustic sounds. Of course I'm basing my observations from what is supplied from the factory.

Both synthes sound awesome and I'd be content with just the Triton and XV3080 (which I own both) at a pinch if I had to sell all my other gear! Cheers.
