Hi Joelstj,
That's a bit difficult, because you have for yourself to build up an opinion on modules. That's why the "homework" of reading, checking and listening at demos is so important to create for yourself a view on a module and after done all that, just buy a few modules (not too many), get experience with those modules and then you will realise that you have to adjust your own opinion on certain matters a bit, once done that you can do a kind of "second round" of checking everything, buy a few modules again, build up experience again and you will again realise that you might have changed here and there a bit your own opinion on how you are looking at modules. That's something you have to do yourself, nobody can do that for you.
To give you a few ideas (and please keep in mind that doesn't mean the rest is not good or not interesting, there is so much that it's undoable to discuss everything):
VCOs: Plaits & STO are nice ones, a simple but good one is Doepfer - A-110-1 for example or the E330 from Synthesis Technology is a nice one too. The Dixie II+ from Intellijel seems to be nice (it's on my wishlist)
EGs: Doepfer - A-140-1 ADSR, simple plain but good, especially to start with. A lovely tripple AD is the one from Hikari Instruments - Tripe AD, I love that one, Make Noise - Maths but you got that one already and also the Contour is doing well
LFOs: ALC - QLFO, Doepfer A-145-1 (I use this one a lot, straight forward but reliable in almost every patch), Erica Synths - Black Octasource if you want to go really crazy but consider this one only in your 3rd or 4th round, this requires some experience with modular synths
Filters: Doepfer - A-124 VCF 5, Wasp filter, fantastic filter, Euporie from I/O Instruments, rather new brand, I just got this filter but I think it's good, I need to further explore this one, Erica Synths - Black Dual VCF --> interesting filter with quite a few interesting options, Instruo - Tràigh filter is quite good too.
VCAs: The VCA I love most at the moment is the Waldorf - DVCA1, it's a fantastic module, Erica Synths - Black VCA is nice too, Doepfer A-130 (lin) & A-131 (log) are good too. Patching Panda - Punch lovely bitey VCA
Effects: Intellijel - Springray II, lovely spring ray effect with up to 3 tanks, Erica Synths - Black Hole DSP2 is not too bad either
For a mixer you could consider the Doepfer A-138p & 138o combination, that's chainable, so if after a while 4 channels aren't enough, just add another A-138p to it and you got yourself 8 channels :-) But it costs HP space...
This is such a small selection of so much there is outside, you really should look for yourself around. If possible have them tested at your local dealer. I have done that (testing of modules) a lot and I had to keep adjusting my opinion about certain modules.
Well that should give you some food for thought ;-) Good luck and kind regards, Garfield.
