Well, Im having trouble deciding, I see that Syndra is ridiculously strong and ranged, but isn't that fun. Zed has incredible burst damage, attacks are cool, but somewhat squishy, and Jayce is really good for poking and harassing. Which champion do you recommend most? plz list in order from best to worst.

Also, one mroe question: Lee sin, Kennen, or Vayne?

please do not troll, or post about any other champion, thank you.

I have not played Zed or Syndra. Fizz is currently my favorite AP carry, and I think that if you're willing to put in the time to master him he is definitely a good pick. He's got great evasion, and devastating burst damage.

Jayce is so-so in my book. If you can nail his gate + projectile combo you have great harass, and the ability to switch between ranged and melee is pretty fun. If you need a decent top in your selectable champions, he's not a bad option.

I would still go Fizz > Jayce tho, I love that little amphibian

For your second list: Lee > Vayne > Ken imo.

Most of those champions play different roles from each other so it is kind of dumb to list them in a better or worse order. It all really comes down to preference and compatibility to your play style.

Syndra is my favorite out of those three but that is just because she is a mage and I tend to like mages much more. Zed is a burst assassin, I like him top quite a lot. Jayce is a melee range, hybrid fighter and I think hes a dick but hes very good played correctly, most champions are.

Out of Lee, Kennen, and Vayne, that still can't be categorized because they all play differently and offer different things. Vayne is my favorite ranged carry in the game, I love her kit because she is one of the best duelists. Kennen is a great mage with an unforgiving ultimate, he can also be played AD decently enough. And Lee sin is best in solo lanes or the jungle, he is a beefy fighter with plenty of sustain and great mobility.

I apologize for not giving you a definitive answer but you just can't do it! At least know what role your interested in, then we might be able to help you pick a champion.

Jayce > Fizz > Zed > Syndra, generally speaking. That's a fairly broad range of roles though, so there are going to be lots of situations where the list changes.

Jayce is very versatile and, in my opinion, currently overpowered. He has a huge number of options at all times and is effective at all ranges and in all situations.

Fizz has good burst damage and absolutely crazy gap-closers/escape, but is otherwise unremarkable.

Zed does great burst damage, but has difficulty escaping after a kill in teamfights. It's also very very easy for an experienced player to counter your ultimate, severely limiting your damage.

There are a lot of AP casters who are generally better than Syndra. Her only two redeeming qualities are a long-range stun (that's difficult to aim) and an amazingly powerful single-target ultimate (that requires setup). Her passive is almost nonexistent, and her Q-spam isn't that useful outside the laning phase.

Second part

Lee Sin > Vayne = Kennen

Vayne and Kennen have roles that are too different to easily compare them, but Lee is one of the best junglers right now due to his amazing mobility. He takes a fair bit of practice, though.

These lists are for high level play though, if you're just playing normals it probably doesn't matter very much which ones you pick. Fizz and Jayce are probably the easiest ones to do well with.
