Firefox Sync is the most infuriating thing ever, how has it lasted this long like this?

Question

I'm sorry if this comes across as more of a rant than a query, but I am absolutely disgusted with how incredibly difficult it is to get Firefox Sync working properly (or perhaps how easy it is to break it).
I opened a previous support thread @ https://support.mozilla.org/en-US/questions/983868 but I was unable to get any advice that seemed to change anything.
I have tried 2-3 more times on the latest Firefox (27 I believe) with new profiles, clearing my sync data, and every possible combination inbetween, and I can never get my devices to sync reliably past, even the "First sync" progress bar fails while adding devices #2, 3, etc.
I got so desperate that I decided to try Nightly's new Sync (Firefox 30), hoping that things would have improved without the need for a Sync key (since I was confusingly getting sync key errors, despite entering it manually). Low and behold it STILL does the same thing, except that now I'm provided with an even more transparent service. I am unable to view my data quota, and Firefox doesn't even ask me for my master password now when I hit sync. That, and it's STILL complaining about the lack of a recovery key, when there is no such thing as a recovery key anymore, what the heck?!
In the course of a few hours I have created dozens of error logs, and this is all by trying to use just 1 Desktop installation and 1 mobile installation. I have probably approached burning over 20 hours trying to get Firefox Sync to work, and it's apparent that the feature is just flat out broken.
Even with all of the errors, some things sync properly like Tabs and occasionally preferences, but other things like history, bookmarks, and add-ons never work after the initial sync (or even during the initial sync). It seems though that the further away I get from the initial sync point, the less reliably these features work.
This may fall on deaf ears, but I thought I'd reach out for help one last time to see if anyone can help, or perhaps point me to a place where I can receive more technical support. If anyone is able to help, it would be greatly appreciated. My logs can be found here

Answer 1

I'm not exactly sure if that's a statement or a question, but it doesn't really pertain to my predicament.
I created an entirely new Sync account with brand new Nightly profiles, the only thing I brought over was my places.sqlite file, as I could not transport my history via any other means (passwords, bookmarks, add-ons, etc I all did via other methods).
The initial sync usually works, but after that things just don't seem to work correctly.
I also ran into another problem in that I cannot delete my sync data via
* https://account.services.mozilla.com/
I also tried deleting the account, which kind of seemed to work as I was no longer able to log in via the above website; however when I tried to create a new Sync account with the same e-mail address, it said an account already existed. I tried logging in to my deleted Sync account via Nightly, and it logged in as if it was never deleted.
