Bloody stool is far more common in cases of UC than in Crohns. Rectal involvement is nearly $100 \%$ in cases of UC (versus $20 \%$ in Crohns) and patients with UC typically experience severe diarrhea. UC is also characterized by a pattern of remissions and exacerbations, while Crohns often has a more prolonged and variable course.
