There's a decent review already available here, if you're interested and don't mind being spoiled.
That said, Euphoria is worse than Fraternite. I can't even understand why people come up with Euphoria, stating it's a good visual novel. No, it isn't. It's really bad, especially plotwise. Fraternite seems to be at least decent and properly justifies a lot of what happens throughout the story. Things have meaning; it's the characters that are the issue.
