70-413 or 70-714 experiences?

It seems the majority of posts here have been focused on the MCSA. Looking for feedback from anyone who has gone on to 70-413/70-414 to complete the MCSE.
I am going to try to move on to these but am concerned with the cloud topics and System Center content, which we don't use much of where I work and are hard to get hands on practice with. I've watched the exam objectives change over the last few months too and have been discouraged with them seeming to be a moving target.
Since there is a lack of good book material I am look an these resources for the 70-413.

If you completed the MCSE, what did you use to prepare and do you have any recommendations on how to best prepare for these?

This link leads to a lot of helpful information:
Try System Center 2012 R2 | Microsoft
including the Virtual Academy, Virtual Labs, downloads, blogs, and plenty of other information. These tests require a holistic approach and are very System Center heavy. After all, certification exams are about pushing a vendors products and technologies.

I am going to use the Born to Learn Wiki, the virtual academy and the Try System Center link above. I went through the CBT Nuggets for 70-413, but they are dated already and missing some of the Azure and system center stuff.
I haven't had much motivation to go back mainly because it requires passing the 414 exam which to me looks like a filler exam that MS didnt know what to do with. Half of the objectives look legitimate, the rest look like filler.
