I’m confused about the ultimate alien episode arrangement.

So originally this is how I thought the 52 episodes were arranged. Season 1 having 20 episodes, season 2 having 12 and season 3 having 20. However in some places such as the Ben 10 wiki it’s arranged like this, season 1 having 10 episodes, season 2 having 10 and season 3 having a whole 32. I personally like the first one more since the whole Aggreggor arc is contained in 1 season.
