Adventure Time: Main characters traveling the world, chill personalities and some quirky, meeting new and interesting characters, saving the world? Small character development
Steven Universe: Main character learning who he is while meeting those who associate with his mom, All gems are lesbians (whole 'nother arguement), a hierarchy with serious power, saving the world, lots of character development
Although these shows are similar, at the end of the day (for me at least), lots of character development wins: converting gems to "Crystal Gems" as they learn to love the Earth, and even the mental contemplation of each of the diamonds

Amazing World of Gumball: Mostly chill characters, inconsistent design of characters, humor, main characters are like ordinary kids going to school, following Gumball and Darwin's day-to-day lives.
Another great show, but personally I prefer the deep emotions displayed in SU. Getting to know the characters, what upsets them, what makes them happy, what other emotions do they display over time?
For example, the diamonds:
Blue diamond is always sad, but she learns to accept Steven which makes her protective of him. Yellow is very stern, but Blue eventually gets to her as seen in the "What's the Use of Feeling Blue" song.
