You are talking tech specs and comparing those to others like the discussion would be about computers. It's not, it's about musical instruments. Like it or not, but the SID gives a very unique sound. There are many big musicians/groups that has used a Sidstation in their productions (Madonna, Trent Reznor, Nine Inch Nails, Timbaland, Daft Punk, RedOne, Robyn, David Guetta, Depeche Mode, Psy, No Doubt, Machinae Supremacy, to name *a few*), and it's quite easy to spot when they do. The reason has nothing to do with tech specs compared to other solutions or price of SID chips on e-bay.
