Are the symptoms the same for each variant of covid? or does each one have different symptoms?

The overall symptoms are not much different for Covid-19 variants, only the severity of the symptoms, especially with the lower respiratory symptoms, i.e. Covid-19 induced pneumonia and ARDS, which are the most common cause of mortality.

Agree with Dr. He. The symptoms are more or less the same, some strains are less severe. Omicron stains causes scratchy throat more than sore throat.
