czech german shepherd or belgian sheepdog?

[Jeff]

I am trying to decide between these two dog breeds and I need some help. I have experience with dogs and exercising them would not be a problem. I understand both doth have a lot of drive and energy , and I like these traits in a dog. Which of these two breeds would be better suited to someone who can reach all exercise and socialization requirements , but will probably not enter either into dog sports or competition s in the future. I have researched both breeds extensively so trust me , I am not expecting a golden retriever.
