IME (from keeping both)
There are some slight differences in physical, fry-caretaking and overall lifespan between em.
1. Bolivian Rams are bigger in size
2. Bolivian Rams live on average more in captivity and in wild (try keeping a GBR for more than 3 years)
3. Bolivians Rams will more readily care for thier fry, and difficult to get a mated pair to raise their babies.
4. this is IMO/IME i'm sure there are more slight diffrences and opinions that go against mine. ok
