Darius or Fiora?

Fiora can carry harder, but Darius is more reliable since he can go more tank than fiora. Is fiora loses her lane, she doesn't do much the rest of the game

Fiora. Darius is useless in every elo.

Darius is better in lower elo and stomps harder, UNLESS you can play fiora very well, in which case she is better.

If you really think youre getting out of bronze pick fiora

If you are bad and you know youre bad but just want to have a chance to escape pick darius

Darius carries a lot harder than Fiora... Take my word for it, or check my ranked winrate with him. He's broken as hell right now and Fiora is extremely weak due to over nerfing.

the better player

If you have played neither champ ever Darius will be better your first 5-10 games than Fioras first 5 - 10.

After 30ish games Fiora will out perform Darius hard.

Darius is a simple champ that doesnt get much better as you play him more, there isnt much to get used to and to abuse.

Fiora is a champ that is chalked full of OP crap but it is a bit more difficult to pull the OP crap out of her kit, so it takes more games played on the champ before you can consistently abuse her OP crap.

If you plan on learning the game and going hard on a champ, pick Fiora, it will be more rewarding. If you are hoping some champion will carry you out of bronze with no effort Darius is probably your best bet

Darius is one of the top 10 best laners in Plat+ with 52.7% win rate and is banned quite often. Fiora got nerfed a bit too hard in the beginning of the season stuck at 47%, and is played less and hardly ever banned.

Your personal skill with a champion will always matter the most - but assuming you're even in skill with Fiora and Darius, Darius is safer, easier, and a straight up better choice.
