Should I farm the event for qp? Or the daily quest is better?

I am planning in farming the final stage and then converting the currencies into qp(of course for the mats too). But I think after the conversion I can only get a small amount of qp. I don't know what to do, so should I stick with the doors? Or farm in the final stage

Thanks mate. Well I'm already done with all the quest and have more than enough ce drops(thanks gacha gods) so I'm aiming for farming qp right now. By the way do you have a mona lisa ce? It seems I don't have any friends with it equipped on their servants(of course their is an ongoing event)
