did you find the design route beneficial at all? I had a look at some videos for the CCDP and it was stupidly basic. Though I was hunting for ideas while designing a network including DMVPN with over 1000 spoke sites so the Associate level exam wouldn't be much use 
)Tbh I'd stick to Wendell Odoms stuff. Bit text heavy, but got me through my CCENT pretty easily.
Both have the same content, however the 200-120 combines the ICND1 and ICND2 exams into one.
You can take the ICND1 and get a CCENT certification. And then take to the ICND2 to get the CCNA. Good if you are also working as you can spread it out over time.
