The enemy of "best" is "good". Some people rationalizes it is okay to recognize Easter because we celebrate the resurrection of Jesus.
We should be celebrating the resurrection of Jesus every day - no need to pick a pagan holiday for the celebration.
Celebrating Passover (Jewish Passover, not Maundy Thursday) is best. Passover is a special time of worship.
You are accountable before God on whether you celebrate Easter or Passover. See my article,
Dan 7:25b OOYLT
... it hopeth to change seasons and law; and they are given into its hand, till a time, and times, and a division of a time.
The ancient Roman Catholic church did much damage in altering the law (bible) and times (holidays). They may had even pulled a chapter or two from the bible. See the essay,
Was Acts 29 Part of the Original Bible?
