Do you think skateboarding or aggressive inline is easier to get decent at faster?

I've tried skateboarding, but I can't even ollie after tons of practicing. Last time I put on a pair of skates was when I was little, but I'm really into aggressive inline. So, I was wondering if maybe I could get moderately ok at inline to just the minor point of it being an enjoyable hobby, as opposed to just frustrating. My one friend has inline awards and was sponsored, but he can't skateboard at all. So, I'm thinking of trying it out again. Do you think it's easier to pick up inline? I know easy is an understatement because both of these sports are ridiculously hard.
