I tend to focus on the overall narrative of games more than individual characters. I've never really thought about characters being "likeable" as necessary for me to enjoy stories. I mean, it's a plus when it happens, but it's also very rare for a character to make a strong "likeable" impression on me.
Squall is a good example. He's a very interesting character from a narrative perspective because of his social anxiety, but I wouldn't really consider him "likable" in the same way as I do Phoenix Wright for example. However, I would consider Squall is still a "better" character than Phoenix Wright, because of how his traits are used to make the story of the game more compelling. (I know this is an apples and oranges comparison, but I'm just using it to make a point).
