My first instinct would've been someone like Teemo, Pantheon or Jax who could completely negate AA's, especially Jax since he scales better late game to compete with Jinx. Someone like Fiora or Riven could easily jump onto her at 6, and completely erase her with her ult (especially due to the recent Riven buffs), but they both require a lot of practice to master mechanically.

Yasuo would be at a disadvantage, since the Randuin's negate's 10% crit damage, and the recent Yasuo nerf which made armor pen only apply to crits, full crit is possibly a must to output the most damage.

ADC's like Ezreal and Miss Fortune who can outpoke her very easily and are very strong early can shut her down easily and gain a huge advantage.

Uh, but to be absolutely safe however, pick Jax. Don't go for trades until 3. Her base attack range is low, which allows you to (remember to activate your Counter-Strike 'E' [insert Valve joke here] before engaging) and Leap Strike 'Q' onto her (or on a minion near her, as the hit box of your E is overwhelming. Use your W empowered auto and at least one more before backing off.

The good thing about Jax is that he scales off of both AD and AP so he can build hybrid. If you get low by any chance, and Jinx tries to use your ult to finish you off, you can just Zhonya's it if your Q is on cooldown/there is no minions nearby/you're out of wards.

Her snare has a relatively high cooldown, so if she snares you, you can just QSS it off and she will have no form of CC to stop you.

If the 1v1 lasts until 6, you have the advantage. Jax's ult grants him armor and MR, which should help against the Guinsoo's passive. Also, the 3rd auto passive on your ult is what makes Jax able to output so much damage even if he's building tanky.

I chose Jax because I'd assume if your friend is that boasty, he'd probs say "gg you can't even win a 1v1 without using a noskill champ like teemo".

Hope this helps.
