Its quite clear that the subtractive synthesiser stole the show when it comes to these two analogue synthesisers. But I want to understand what it is about the subtractive synthesiser that makes it more favourable from the eyes of a designer. Is it easier to design/build? what are these factors?

Additive synthesis depends on numerous oscillators to generate the required harmonics of periodic waveforms. When too few are used, the sounds can be lackluster, lifeless, even dull. Still musical, but without crispness normally associated with analog synthesizers unless a very large number of oscillators are used. This is easier to do in the digital domain, but still requires a substantial set of resources to do it "right".

Subtractive synthesis starts with waveforms chock full of harmonics. A single fairly simple tool - the filter - is used to remove harmonics as needed or desired.

Subtractive synthesis is simpler, smaller, easier and less expensive than additive.
