I'd say that this subject cannot be debated as better/worse in any case... it's like with any other form of art, it's a personal thing. If analog was absolutely better, then why do we see so many digital synths coming out, including workstations etc? ... There MUST be a widely different opinion spectrum on this matter.
To say that either is better than the other, in my point of view (when said in a general fashion), is just arrogant... straight out... in the end, it's what you make with your tools that matter, not what tools you use to make your stuff.
Yes... digital has some things that usually makes you wish it was better... one is aliasing, since many digital synths have problems in the higher frequencies... but then again... analog has problems doing stable FM synthesis, and is not even capable of doing what a DX7 does... yes, analog has a good and great potential for bass sounds for some obscure reason compared to digital, but then again, highpitched clangorous bellish sounds they loose to a DX7 too...
So in the end... what you feel is "best" is just usually the stuff that compliment you the best, and makes you happy... those features might make other people not even care...
I found this out the hard way myself lately by the way... When I began my synth route many many years ago, I was totaly into digital synths... I thought that they had digital outs, giving cleaner sounds, more features, more polyphony etc... but then I started doing more techno/trance type of music, and found that ONLY analog or at least hybrids was THE BEST! ... and it was... for me, since the music I did, called for it...
Then recently I've started doing Ambient stuff... and now I really see how bad analog monophonics really are for this genre... the sounds they do are limited in that genre's favor... it can be done, but require substantial FX outbord, and getting any pad sounds out of them is just impossible... Ambient call for all kinds of weird sounds, and with loads of polyphony... suddenly, all the FM synths, the wavetable synths, the ROMplers, samplers etc. has risen in my awareness again, and I've had to accept, that digital synths are much better now than they were before... because I need their type of sound and flexibility.
This has made me sell my monophonic analog synths lately, and begun getting digital synths again... keeping only the polyphonic DSI synths... My Pulse 2 is going... My MOOG Sub37 is going... now I'm investing in a Roland Integra-7, and I'm on the hunt again for an E-MU sampler etc...
So please... this outdated debate about analog vs. digital... it really IS pointless, if you do not take peoples goals with their music into account...
