Which melee adc (usually top lane) scales the best to a teamfight
Please do not write Nasus I do not consider him good personally as he gets kited.

Fiora has great ult for teamfights, but gets wrecked by thornmail... Yasuo is the greatest teamfighting carry, because he has AOE, mobility, wall + some cc, but most toplaners counter him, he can't survive many toplaners like Pantheon, Darius, Renekton etc. He actually can do better botlane with the support than top, if your ADC can go top vs their bully, because his kit denies range harass, while he can push the waves with the tornado
Trynda gets kited with slows and stuns, Jax can do well in TFs, if can land his stun on several people, they will try to kite you too, so better splitpush; Trundle gets kited, can't reach anyone; Yi has to wait for the major CC to be blown to go in; Riven can 1v5, if she has flash and the enemy is stupid; GP can ult, use one Q and die :D Rengar can 1v5, if they don't have stuns and pinkwards Shaco can kill the ADC/APC and die Xin will get kited Poppy must have ghost up and she will blow someone with 1 Q Nocturne and Aatrox are too squishy, if they go glasscannon and try to manfight Vi can do it, because she builds tanky, still does insane dmg, has CC, shreds armor ADC Zed (crit Zed op) dives the backline and murders the mid + sup and ADC, ignoring the tanks (doesn't really work vs competent supports) ADC Katarina is just fed, trolling Katarina that sold her AP and now 1shots you not only with ult and W, but with autoattacks too - don't feed her next time
Nasus' kit in general conflicts with the idea of grouping up and teamfighting.
Tryn/Fiora are probably the absolute worst, but I don't mind Irelia. She only has 1 stun, but you build her tanky after 1 dmg item typically, so she has a bit of everything going for her.

Irelia Jayce
Both are a bit hard to use. Jayce will be receiving nerfs soon so use him while he is op
Why is Jayce getting nerfs? He's not even OP.
Yasuo if you have some knockups in your comp to support him.
He is OP Long range fast moving AOE poke is too good on him with mana and Cdr
They already addressed the problem with Jaycee and varus
If you mean melee adc as in a melee champion who builds glass cannon crit, Yasuo has probably one of the better teamfights (hard CC), followed probably by a good Yi or Fiora (massive AoE and resets).

Aoe Crits, knock ups, projectile blocking, and massive damage and mobility combine to make Yasuo a much better teamfighter than Poppy until Poppy has gotten to LATE game (as in 6 items).
A Top Lane Melee ADC who scales the best for a team fight? For team fighting, probably
.
and
are more duelists than good team fight melee ADCs, although a really good Fiora can pull off some decent AoE. I would still go with Jax since even if he doesnt do well, he still is pretty dang tanky and has an AoE stun for team fighting. The rest of the Melee ADCs dont usually go Top Lane, except for Aatrox who is painfully subpar at everything except for sustain, which he isn't even the best at. A jack of all trades except, unlike Lee Sin and other similar champions, his main "trade" isn't extremely noticeable past Middle Game.
Riven and Yasuo are probably your best bets. Both scale well and can carry hard even in teamfights. Yasuo requires more help from his team, but gets an awesome wombo combo with champs like Malphite. Riven (if you're good enough) can win most lanes with a bit of help, and then snowballs massively allowing her to go against a lot of enemies at once, though her teamfighting is really more of "My team fights, and then I go in and clean up the mess, picking up a penta".
fiora is she snowball a bit. if you can go with q and get an ult of before you get cced and insta deleted then she is really strong. but poopy is ofc the strongest melee adc/assasin late game teamifghts

Nasus isn't a melee ADC, so I don't know why I would.
Anyway, Poppy. Once Poppy gets enough of her build finished she pretty much eliminates the very concept of a "team fight".
