I've backed up and restore onto the new iDevice every single time without ever seeing any performance issues.

Performance issues relative to what? How would we know that performance wouldn't have been slightly better with a fresh install? I did a restore both times I upgraded my iPad, but it wouldn't shock me to learn that a clean install would have yielded fewer crashes and speedier performance. There's really no way to tell other than some type of measurable regression testing with two new iPads with the same apps and content - one restore and one clean install.

In trying to rectify the iPad Air crashing, I have wiped it clean and run it without any apps loaded. It was still crashing (pre 7.1), and was no faster than restoring from my backup with all the bloat, not that I could detect in actual use anyway. I'm not going to run a benchmark or use a stopwatch to time it - if that's what it takes to see a measurable difference, then is it really worth reloading everything from scratch?

Probably not... which is why I took the lazy route and did a restore. But I'd be lying if I said I didn't feel a little guilty about it. There's something comforting about starting over.
 
You know,what else does wonders. Shutting the damn thing off. One day a week, shut it all the way down and leave it like that for a good 20 minutes, if not longer. Go take a walk.

Keeps you from turning into a total WallE human as well
 
I just factory restored my iPad.
Not because it seemed to be running slower, but because that ridiculous "Other" was taking up a big chunk of my 16 gb of storage.
Yes I always delete my iMessages and email.
I REALLY wish Apple would include some sort of utility in iOS to clear caches or whatever "Other" is.
Shouldn't have to take the time to wipe the iPad and reload to do that.
