As an electronic musician, I love synths AND samplers off course.
It's just that in the mid to late 80ies, samplers and PCM/sample-based synthesis were all the rage (see Art of Noise, Yello, Janet Jackson and the way her voice was sampled and cut, etc). So the Amiga was very very forefront with that. At that time, all the synth chip based solutions sounded very oldschool to me.
Off course, now in hindsight Paula is a kind of shit sampler, and SID is still an amazing unique sounding synth, though..
