“We find no evidence (for both risk of hospitalisation attendance and symptom status) of Omicron having different severity from Delta, though data on hospitalisations are still very limited… Omicron was associated with a 5.41 fold higher relative risk of reinfection compared with Delta.”

A new preprint out from Imperial College in London says there is no evidence that Omicron is any milder than Delta, and is significantly more likely to lead to reinfections.
