I mean thats up to you man. If I was you, I personally would. But that is because I would rather be on the front end of this whole process rather than feeling overwhelmed and under prepared.
In fact I DID do this. So far it has worked out for me.
The extra time of the extra year helps you boost your ECs and your app, and allows you to get your crap in order and then be able to get it all in on day one next cycle. I would argue that this will allow you to get into a better school.
But then again, I am only 24 so I am cool with this. Others are not so cool with it and would rather at least take a shot at it. People in your situation have definitely gotten in (depending on your stats). But again, I imagine it is a lot more stressful and you wont have as high of a shot at some of the better schools, and in the end you will likely have little to no choice in what school you attend. You will end up taking what you can get.
AND if you DO get accepted to a school but then decline it and try and apply next year (to ANY school), it is a big black mark on your application. So while you may say that you are cool going to any school, there are massive differences in price, quality, mission, and location at all the schools. These differences can cause even the most positive people to feel unhappy if they are clearly in the wrong situation.
So with all of that stuff in mind, I ended up postponing my application last year until the next cycle (this cycle). I got my crap together day one and so far already have 4 interviews lined up. I feel pretty good about my chances of getting in and I feel good about the fact that I will hopefully have some choice in the matter of where I will attend. I would give up 9 months of waiting for the security I have this cycle, any day.
