This whole thread has become an April fools joke. Every imagined advantage to FF has been repeated, true or not, researched or not. But ti was a great option poll. My last word is probably to compare an FF with an 8x10 or 4.5 film camera. If you can carry it, and manage the weight, you might like it. If you shoot wide DoF at a distance, it has very little to offer. You can buy more MP in FF format than you can with APS-c if you need that. But the truth is, 99% of the people here wouldn't don't need it. Most of the people here don't need 12 MP. The rest of it amounts t two baseball players sitting in a dug out. One uses a 27 ounce bat, the other uses a 28 ounce bat. One says, there are advantages to using a 28 inch bat the ball goes further when you hit it. The other guy says, You have more chance to hit it with a 27 ounce bat, it's lighter and more nimble in your hands. They both hit the ball out of the park, once the ball clears the fence at 300feet, no one cares if it goes 325 or 350 in the air. They are both a home run, you get one run on the scoreboard for both, there is no bonus for hitting it further. The guy with the big bat strikes out more, the guy with the lighter bat has a higher on base percentage. You want both guys on your team.
Go hit some home runs. And if you're a photography enthusiast and you can afford a bigger format, buy it, you'll enjoy it. Even if 90% of the time it sits in the cupboard. And that goes for every larger format going on up. DOn't stop at FF. You'll be missing out.
But don't pay too much attention to what most of the people here say. If you buy an FF, you'll make it work for you in your own way. A lot of what you read on here won't be important, but some other things that you don't think of now as important will surprise you.
All some people need to excel is a little bit of confidence. If talking up FF and owning one give you a little bump in that department, it's worth it.
Just don't become one of the morons who has the next booth over to me at the craft who's and tell me how much better your camera is than mine and what FF I'd really like, but isn't selling as much as I am... Or one of the idiots who comes to my booth and asks where I took my pictures then plots and plans with his buddy to reshoot the ones he likes, because they'll be better shot with a full frame. 90% of what people believe about FFs, isn't true.
Buying a full frame gives you the opportunity to explore some unique photographic opportunities, in narrow DoF. Beyond that it give you the opportunity to shoot in lower light by reducing your DoF. But you can do that on APS-c just as effectively, except for the wide open ƒ-stop on every lens.
