It's pretty shitty to have to wipe out your data just to get it to function like it should.

It might be shitty, but a good analogy is if you bought a PC with Windows 95 on it, would you expect to upgrade to Windows 98, keeping all your apps and data, then upgrade to Windows XP again with the same apps and data, and have everything work fine? You've gone 3 generations of software with the same data. Those SQLite tables (CoreData) probably need to be optimized in some way, and the easiest way to do that is start fresh and do a new sync. Or just live with your slow phone; either way I could care less.

What would you lose? Refraining from restoring from backup does not mean that you can't still sync your data in iTunes afterward.

I didn't say you would loose your data. I said wipe out your data with the implication of it being wiped off your phone.

That being said, maybe my understanding of how iPhone updates happen is a little flawed. I'm not too clear if it wipes your phone clean and then resyncs everything after the update. Or does it keep your data on the phone during the upgrade?
