JoRillo, I can appreciate your enthusiasm in getting into this whole 'audio engineering' thing, but seriously the worst thing you could do is to rush into any purchase without even knowing what your buying. I definitely don't want this to come across to you in a bad way but don't let any money that you have right now burn a hole in your pocket.
Beatsmith is right, these two SSL products are completely different in what they actually do.
Stay here on GearSlutz - read up on as much as you can, and try not to ask questions that have been done over a thousand times already as the long established community that frequents this forum will get sick of you pretty quickly and you won't get any answers to your questions.
Questions like "SSL Nucleus or SSL Matrix" come across to those 'in the know' like "what should I get - a shirt or trousers?", well what do you need a shirt or trousers, two completely different things which serve completely different purposes.
Judging by some of the threads that you have already started it is very obvious that you are fresh into this field. Give yourself a couple of years at least in researching, learning off of others and building your experience with as minimal amount of gear that you need to accomplish what you are currently working on, or else you'll find that if you do rush into anything you'll probably end up with an expensive piece of gear that you don't even know how to use it to it's full potential and end up selling it and losing a heap of money in the strive to find what it is that you really want.
If you want to control software faders and also have a few inboard pre's go out and get a 003 or something, they can be have pretty cheap nowadays and will serve your purposes nicely (for now) - you'll have fader control, monitoring, on board pre's, enough in's and outs to keep you occupied for a while, and you also get the 'wow' factor from clients (friends) who come into your new project studio and admire the flashing lights and moving faders

- and although they are a bit older they seem to be built better that most of the 'in the ballpark price range' controllers out there at the moment (ah la Avid Artist Series - which don't have the on board pre's or monitoring anyway).
Like most Gen Y's I know you want everything now, now, now. But recording, mixing and producing is something that only a lot of research, a bit of time and a ton of experience will get you good at doing - stick with it and in a couple of years when you are aware of the amount of sh#t that you need to know you'll be like, wow, I sounded like such a noob back then when I first got into this game
No harm intended, your choice to take the advise or not.
