Just done a check in Stansted & Heathrow web sites and identical prices, so that's the price and will not affect your choice of departure airport, what did make me laugh was the Ryanair advert encouraging you to book for Easter, really......
MOL come back to me at Easter to even consider anything later in the year, even with tempting low prices. You should be budgeting for S21 being a rightoff as well and if things do drastically change then it is a bonus.
