After reading the whole thread, I wonder why nobody ever mentioned the "mV" data, as depicted in multiple screenshots (last one from MonkY).
Those figures seem to suggest that the original OEM battery shuts off at ~3.6V, whereas the other ones shut off at voltage levels as low as 3.3V.
IMHO, that is the real difference between those batteries. You certainly get more mAh if you discharge your battery to a lower voltage level, BUT this has to hurt longevity... 3.3V definitely is not healthy for LiPo batteries!!
But as long as power levels between 3.3V and 3.6V are sufficient for the device to work properly, for me this tradeoff seems to be quite acceptable. A new battery every couple of months seems to be fair deal if you really get more uptime

Humm. Good point. I have no picture, but if I recall well my testing, I'm afraid all Gold, Anker and Samsung had circa 3300mV when at 1%, so I believe they shut off at the same time.
My thoughts are that those three batteries are almost the same... Maybe, the Gold and Anker squeezed 2600mAh instead of standard 2500mAh from Samsung, as I recall I get pretty similar timing on normal usage. But that's it, nowhere near the labelled 3250mAh...
I suggest you guys do your own tests of usage time, but make it reproducible like contant drain e.g. full power and let the same movie or game running with screen always on. I would be surprised if you get more than 2%-4% better with Gold.
So to me, Gold & Anker are good "replacement" batteries, but not improved batteries.
Hope this helps.

Although i wanted to do some extra testing in the weekend with all 4 batteries, i was so amased about the 3250mAh beeing alive even after 2 days of normal Note usage... that i've decided to let it run down to 10%. And the result, as you can see in the screenshot is: over 3 days and 2 hours! I know i haven't used the Note as much as usually (only 3hrs display - on Auto with higher values, and 2 hrs of 2G talking, wifi always on), but i can't believe it lasted over 3 days! With the oficial one, i was NEVER been able to get it last through the second day... not even with less than 2hrs display usage. So, i'm really pleased with this battery for now... and i don't actually care about ppl saying it's just a "placebo". For me this is the best battery i could find (except the 5000mAh one... but that's taking the bulkiness of Note to a level of "unusable").
P.S. I was one of the lucky guys that actually received the battery from lovetommorrow (and got two touchscreen pens as a bonus)
Good to hear you're happy with the Gold, I also think they are good replacement batteries. But, to me, the test you are doing is not fair and reproducible, there is too many unkown things that happens that you can't trust the test.
Looking at your first and last picture, I see that the Android OS was eating more power than the screen and you had the phone in deep sleep for 94% of the time... If you have time to test, let the phone sleep the same with standard Samsung battery and you'll end up have 3 days of sleep as well ^^
If you don't want to spend too much time testing and enjoy your Note, do like me, do a stress test and you might see that under 100% heavy stress test, both Gold and Samsung will sustain 3H10 or something.
