UPDATE: It took me a while to get comfortable around BB. Its such a powerhouse. Navigation and setup of DN+BB setup is not confusing anymore and i can get to where i want to easily.
Once you know your way around, integration is really good.
There are a lot of usable audio and midi routings, so you ought to find something that works for you!
Both can sequence each other if needed, but since both have song mode, can just play along with no extra work. Ability to cross-use sequencers between DN and BB, while they are also playing their own parts, is super useful and fun.
During learning time i was sceptical about my choice of BB over DT, but it was worth the extra time i had to spend to understand a different structure.
Now the fun part, learn how to make samples sound good 
P.S. This marks the end of this topic for me, but if you stumble upon it and have questions about running DN+BB together, feel free to ask.
