As a example will use same bullets flat nose and roud nose .. which number is supposed to be better the higher one or the lower one .. is the higher the number better..? Thank you. 
Im trying to understand BC

Bc with higher number is better. However the bc is not constant as it change with speed. In your example the 60 gn has a bc of 0.181 and the 61 gn has a bc of 0.169 .

Not related to your question but I will say it anyway.
The higher BC projectile (any) not necessary more accurate?

The higher the BC, the less wind will affect your bullet and the more energy it will retain down range. As above, it does not mean you will get smaller groups.
BC should not change with speed, but it often does due to manufacturers using unsuitable reference drag laws for calculating their BC values, often giving inflated values at high speeds. Good for sales, but not for accurate trajectory modelling.
