What should I read First Destiny War or Brothers in Arms? (Serials)

Okay, so I haven't read either of these serials, but quickly scrolling down the copy and pasted Microsoft Word document that I created so I could read it on the go, I notice that after chapter 6 of DW it tells me to continue the story to Chapter 6 of BIA, and after Chapter 5 of BIA it tells me to continue the story in Chapter 6 of DW! So, my question is, in what order should I read these serials? And for deeper discussion, are they even worth reading?

A tough choice...

Honestly, I'd do the least longer one... Unless they're both the same in length. If they are, just go with your gut.
