This is a very long string, so this question may have been answered

I am currently a OP member but also have a WP account. My status is with OP as is my miles (I have a lot). Is it better to accumulate miles in one ST account or should I have some miles in 2 ST accounts? Or is it better to have one ST account and a different affiliation such as oneworld. I have an account with US as well, so should I join e-miles with US or CO or NW?? If this has already been answered please direct me and I will read. Thanks for your time. BTW, I fly all 3.
