Forum:Which champion should I get?

Jayce or Syndra?

So I can buy either Jayce or Syndra, but I'm not sure which champion to buy. I haven't played either, and I don't really want to wait until they're both free since they both look so fun. I have a lot of AP mids and barely any top lane champs, but Syndra just appears to be more fun and rewarding but I'm not quite sure.

Also, I was reading about Fiora since I've seen her top lane, and I've been told that she's one of the worst melee champions and isn't worth even trying to master but she does look fun and her ulti looks strong, so would she be worth buying, too? If so, is she better than Jayce?
