This is the craziest poll question I have ever seen. You have asked 2 different questions, but we can only give one answer. I personally would say acting would be the easiest of them all, mainly for the reason that you are able to work from something that is mostly there already. That and you have someone there telling you what they are wanting from you. I am in no way trying to imply that to be a good actor is easy, but actors can always try to put off their bad performances on a bad script or bad directing.
For what I personally think is funnest though would be screenwriting. I have so much fun writing new stuff, even if I know its kind of stupid. I just enjoy being creative. I would like to give acting and directing a try too, just for some fun on the side.
