the version you used is in bit 3, not 4.
hey op, i suggest to wait for another year if you want root, don't try to go back android 9, or else you will get bricked.

I had my Note 3 AT&T bricked and stuck in bootloop too, from Android 4.4 KitKat OTA upgrade too. The method linked below helped me to unbrick it, but note that it's based on the KitKat version leaked from AT&T in January, and it will not take the official OTA upgrade, nor can you downgrade from it to any lower version. Folks are working on a way to upgrade it to the official OTA, and independent work is done on rooting, I'm sure, but for now I'm stacked with the "leaked KitKat". Nevertheless it works very well, no issues with it whatsoever. Even my biggest complaint against version 4.3 - the GPS issue, is fixed now. Read more about this unbrick method at:

might be because there are no 4.4.3 note 3 there are 4.4.2 note 3 but if you are trying to downgrade the 4.4.2 nc2 ota it cant be done if you are trying to downgrade the leaked version use the mj5 restore in the general section

Att note 3. Need root help.

I want to root my note 3 so I can download and use game guardian or something similar. I'm on android 5.0, do I got to downgrade to get root access? If so could someone help guide me?
You must flash 4.4.4 kitkat then you can root and flash another rooted ROM or a rooted 5.0 lolipop.
I first tried this: http://www.droidviews.com/update-att-note-3-with-lollipop-ota-and-root-it/
But now I just decided to get a custom ROM (Has a Google Play services problem): https://forum.xda-developers.com/note-3-att/development/10-11-15-t3223180

I think you can just flash stock firmware.
sorry
I'm sorry sir forgive me
However, you WON'T get back the KNOX warranty void to 0x0 it will always show 0x1 letting anyone who knows how to get to bootloader that it has in fact been rooted or the software altered...
Once you root a Samsung device (Exynos) it sets off an e-fuse that shows it has been altered as you would have unlocked your bootloader and altered the recovery partition too.
You may not receive OTA updates because of this...
I have an international Exynos Note 9. Just tried both methods described in this thread.
Method #1, using TWRP - the result is the phone shows as non-rooted.
Method #2, using pre-rooted kernel via Odin: the result is the phone is stuck in a boot loop.
As of now (2 hrs later), the phone is still in the loop, and using Method #1 does not seem to be working either now. Have I bricked my Note 9, where should I read on remedies?
Also, why didn't Method #1 work? I followed the instruction to the word.
Appreciate any insight.

I don't have the "how to" answer for you. However, since you aren't on AT&T's locked bootloader, you can downgrade to any stock ROM you like. In either case, backing up your data, is a must.

You can only downgrade if you use the same bootloader version you're on bootloader version 5 so you cannot try to flash any bootloader version below 5 it must be 5 or above! @Anonymously_Unknown is incorrect when he stated your bootloader isn't locked because your bootloader is locked unless you have the F version which you don't have. You have the American version not the international F version. Also you need to use the newest version of Odin available.
Thanks for the clarification
