Been a while, but I can answer my question myself now because I have taken both
SSI S&R:
Very good course. You learn to cope with stress and learn to recognize stress in your team so you can deal with it before it becomes a problem. A very important an valueable skill. Besides that, you learn important rescue techniques. Combined with EFR, it makes you a better and safer diver. It also makes you a better buddy because you're much more aware of what's going on in your dive team. I recommend this course very highly.
GUE Fundamentals:
Best and hardest course I did in my diving career ever (and maybe ever will do, planning GUE Tech and Cave ). This single course changed my perspective on diving. Meaning: how I dive, with whom I dive, how I configure my equipement, what gasses to use, what dives I make and I don't make, what fin kicks to use, etc. This single course made me a much better diver. It tought me advanced diving skills, but most of all: it enhanced my awareness as a diver. Diving to me is no longer about diving itself, but about enjoying myself under water while having good skills. I actually plan skills dives these days so I can enjoy the 'real' dives I make.
These courses are two very different courses. S&R is aimed at stress prevention through recognizing stress. Fundies is about increasing your skills level and therefore reduce stress through training. Personally, I advise to take them both. Just one thing bothers me. The way skills are taught are not exactly the same. SSI an GUE have different visions on how to do things. You will need to work that out with your instructors.
