Euromaidan was a protests because Yanukovych didn't act on his promise to integrate Ukraine with the EU. Protesters were upset because that was not what he promised during his campaign.
The storming of the capital in US was under false claims that the elections were stolen.
There is both evidence that the elections were not stolen, and evidence what Yanukovuch said during his election campaign were not his actions. You can't tell the difference between the two?
Plenty of protests ended in the fall of a government and electing a new one. Why would that be the same as the US storming of the Capital?
If you would have said to compare it to the Georgian protests that don't accept the election results, that would be more difficult. But Euromaidan? That's easy.
