I have opened the same discussion before, but couldnt find a really good answer. Some said lucian because jinx has no escapes and she got nerfed, some said jinx because she is still op.
I need really good explination to which one I should choose- cons, pros, possible nerfes and overall fun with the champ. Any help would be AMAZING :D
Jinx Pros: Good Range High Splash Damage Late Game Easy to get more kills in a fight after you get 1 because of passive Easy to siege with
Cons: In the tank meta there is a lot of hard engage that makes it difficult for jinx to attack safely Lack of escapes so she cant do much when an assassin is on top of her
Lucian Pros: Mobile Nice Early Game Very Good 1v1 Potential
Cons: Low Attack Range hard to siege without shields to keep him safe requires more skill to play well
In my opinion just pick one and then buy the other one they are both really good champions I think 
are the top 3 ADCs (
are good in tank meta) across all the metas I've seen
Jinx: Hyper carry, good dmg dealer late game. She is not mobility until she score or assist a kill in teamfight. And she have flat chest lol.
Lucian: Assassin-like adc. Not so good if the game last for long time. I love assassinate (and big boobs), so I suggest you got Lucian.
I main Janna - IMO Jinx is worthy of being banned, and is on a tier far above all other ADCs.
Lucian, meanwhile, is in my opinion literally the worst ADC. That isn't to say that you can't succeed with him or he doesn't have his matchups - but in general I cringe when I see him picked on my team and grin when the enemy has him.
Here is a random source to back up my anecdotal personal experience: http://champion.gg/statistics/#?roleSort=ADC&sortBy=general.winPercent&order=descend
get on NA then it might matter
Jinx- Pros: High damage, good push, has CC, AoE crit, good chase with passive, scales amazing, great teamfight
Cons: immobile, easy to catch, close range ult is a bit inefficient because of how the damage works, can be punished early easily, summoners are only true escape (not relying on passive proc as you run away), needs a good amount of peel as well as knowledge of positioning, not alot of dueling potential
Lucian- Pros: Lane bully, good pushing, has escape that resets, double shot passive, passive and BotRK is one of the most effective ways of dealing with tanks (BOTH shots use BotRK passive), decent scaling to mid-late game, fairly simple and safe to play, very forgiving champ overall (can make a good number of missteps and still be fine), good duelist
Cons: Doesn't scale amazingly, ult is awkward to use in certain situations, needs to know when is safe to E forward (good knowledge of positioning), teamfight isn't overwhelming (isn't bad just average)
I have probably missed things, personally I would recommend Lucian, easier to lane bully setting the enemy behind making your front line more effective as well as with Blade of the Ruined King passive % HP bonus damage being applied on BOTH shots of Lucian passive make him very effective at removing tanks from the fight.
