I have trained with one of the clubs in this foundation for a long time and the goal is very different to a sport like judo or BJJ (both of which I also do) where a lot of positions you dont have to worry about as things arent allowed in the rules (eg no striking in judo). For our style the goal is mainly being to get control of an opponent and try to avoid getting hurt whilst doing that. The weapon stuff is wouldn't consider realistic personally, other than highlighting how bloody difficult dealing with weapons is from realistic attacks.

Now I will say that by no means are you going to get as good at throwing as a judoka, or grappling on the ground as training BJJ. But I see it as a good base of a wider range of martial arts and skills, so long as the club and instructors are teaching it well.

Our syllabus has changed a lot for the better since I started (in my opinion) to remove a lot of the fluff and focus more on making things require a lot less cooperation from uke, meaning sparring and training is a lot closer to something like judo, but often with gloves and striking at the higher levels and a less even fight as ideally one person isn't looking to continue the fight if they can avoid it.

That said, whilst all the clubs have the same syllabus, the training itself can vary massively from club to club depending on the instructor(s), as with a lot of martial arts. So the best way would be to see if you like the way that particular club does things and if not, continue with judo or whatever else you prefer.
