I don't get the whole "Virus vs Everything Else" mentality. I have a Virus TI
Snow and I used to have a Blofeld. Ended up selling the Blofeld to try out some other gear because of the MIDI sync problems. I figured if I want an approximation of that sound again, there's always Largo.
Really liked the Blofeld sound. You can get some nice wide pad sounds, old school analog sounds and interesting wavetable sweeps (the wavetables are more interesting than those in the Virus). In terms of modulation options, it's far more flexible than the Virus (16 modulation slots + all those modifiers, it's crazy!).
The Virus sounds great too, but it's not in a totally different league than the Blofeld. Even the Snow (not to mention the TI2) has much greater polyphony, up to 4 stereo outputs (3x USB+1xAnalog) and the VST integration of course, but in terms of synthesis power, they're quite similar but still different.
