With Bastion of Twilight, Blackwing Descent, and Throne of the Four Winds now out for over a week, we decided to take a look at the group data for their launch week to see statistical differences between all the different raid difficulties now present in Cataclysm Classic.
This data was collected by Warcraft Logs from May 30th to June 3rd, with the specific snapshot of data below being collected on June 4th around the weekly reset time.

To start, we can look at the number of kills on Heroic for both 10 and 25-player modes.
10 Player Heroic Kills
25 Player Heroic Kills
In both difficulties, the easiest boss to begin progression on is Halfus Wyrmbreaker, with over 2100 kills on 10-Heroic and over 1800 kills on 25-Heroic.
After that, the next step seems to be the first five bosses in Blackwing Descent, with Magmaw and Atramedes being the easiest ones, followed by Omnotron Defense System, Chimaeron, and Maloriak. While the progression happens all in Blackwing Descent, Maloriak has half as many kills as other bosses, but the progression is fairly linear.
The next step in the difficulty curve is Valiona & Theralion and Conclave of Wind. After that, difficulty ramps up, and discrepancies begin between 10 and 25.
For 10m, Al'akir seems to be the easiest choice here, followed by Cho'gal and Ascendant Council. Note that while all Heroic bosses are required to kill Sinestra in Bastion of Twilight, you can kill normal Ascendant Council and then Heroic Cho'gall, which seems to be the choice for some guilds, as Cho'gall is easier and the loot is superior to Ascendant Council. The final bosses then are Nefarian and Sinestra, both with around 110 kills each during week one.
For 25m, Al'akir seems to have a similar difficulty to Sinestra and Nefarian, leaving Ascendant Council and Cho'gall as the next step after Conclave of Wind. After those, then 25m raids
