I personally like him. He's a chill guy that doesn't stay mad when Daria messes up and Daria grows as a person during their relationship. They have a common sense of humor and i enjoy watching them spending time together.
Spoiler for the show finale "Is it College yet?"
I found it sad that they couldn't go to Bromwell together and i found it sad that Daria broke up because she expected their different societal class to start becoming a hurdle during their time at their respective colleges. It was good to know though that Jane and Daria would spend their time together in Boston.
I really liked all characters but if i had to pick a worst character to save my life it would be Charles Rutheimer for frankly obvious reasons.
