Hillary conceded late that very night of her election. (Even though there was Russian interference in the election and a Republican head of the FBI spoke out against policy that they were reopening the emails investigation.)
Trump never conceded and continues to openly state that the election was totally rigged and stolen and illegitimate.
There is no comparison. Everyone has the right to claim it wasn't fair or that the other side cheated. But when the courts have decided, you accept the decision and you concede and you say you support the candidate that beat you and you wish for their success.
