Well, the actual event in general, catching the candies vs. picking up the eggs felt like it required a little more "skill". I'm probably just saying that because I appreciate hitboxes and details because I spar a lot though. I just had more fun learning how to one-shot the candies with the net rather than brainlessly farming Pyrats for eggs.
Also, the way the prizes are structured felt a lot better. In the Easter event, you're kind of trapped collecting 50 eggs. If you ever get bored or don't want to finish and you have 40 eggs, you get nothing. With the candy thing, people can set their own goal or do it really casually and still get prizes. If it ever gets boring, you can just walk away from it without feeling like you missed out on something.
It's not perfect but if I definitely find it to be more enjoyable than the Easter event. I'm sure the vast majority will say the same thing, but I'm pretty sure it's just because the Halloween event offers way, way more prizes (which is what I think almost everyone cares about the most).
