While it's true that Muff's is a lot more active, people are present here as well...
It's hard to assess a large jumble of modules without any context... what kind of music, what's your experience level w synths, will this be a mostly MIDI setup, are you getting much of this all at once?
Generally all the questions are best answered by the user him/herself - start slow, buy a module or two at a time and then make your next purchase based on what your music needs. Often I think people buy giant systems and then get quickly overwhelmed & frustrated.
The basics looks good - Maths, anti-Osillators, Disting for computer control & special functions, a Pamela's workout, and an O'Tool so you can see what you're doing (the ADDAC dual oscilloscope seems redundant!) Pico oscillators seem a bit stripped down - maybe best to match the Anti-Oscillator ("auntie") with another Richter oscillator ('unkle'), keeping in mind that these Wiard "Griffin" designs are out of production. Circuit Abbey's been having problems lately, so you might have to buy those ADSR's used if available. If you're new to modular, the Control Forge, while often lauded, may just be too complicated for a beginner. You might also want to explore more modern alternatives to the RCD/SCM - maybe just a 4MS Peg instead or a QCD.
On Muff's you'd hear the standard "you can never get enough VCA's!' - you might consider the new Intellijel quad VCA. If you're going 'classic' with the Wiard stuff, you might also want an LPG - like a Wiard Borg or Boogie (both out of production with matching Griffin's, but often available used) or perhaps a Makenoise Optomix.
Just a few ideas - if you just go slow, develop the system organically based on what you really need, you'll probably have a good experience
