In my opinion, yes, but it is a matter of preference for sure. Two oscillators tuned closely together and one oscillator with it's pulse width being modulated both create motion in the sound, I usually prefer the Oscillators, but PWM is a sound I know and love from old video games. To me, the Neptune and to a lesser extent the Mono Lancet would have me creating "bigger" sounds, while the Dark Energy offers a lot more options for quirkier stuff right off the bat. This is just going off of features without hearing the timbre of the unit in person though.
For what it's worth, it looks like the breakout box for the Mono Lancet adds PW CV inputs, but it doesn't look like you get an LFO to control them with - and for the Neptune, the Service Manual describes how to add PWM (and other cool stuff), though it seems like it's something you'd want to have a tech do unless you have experience fiddling with boards and all that: http://www.spectralaudio.ch/support/Ser ... tuneII.pdf
If you're still not sure if you'd prefer multiple oscs or PWM, maybe grab a simple soft synth VST like Synth1 or something and see what's actually more important to you? Try playing around and making patches using only one Osc w/ PWM, or two Oscs with no PWM. You could also use this to decide how important seperate EGs are (simulate only one EG by limiting yourself to setting the Amp and Filter EGs to the same setting, or only using the filter EG and setting the amp EG to min attack, min decay, max sustain and min release, or vice versa etc)
