Which is better in low elo. Yi or shyvana?

DISCLAIMER: Everything works in low elo. So Yi is the stereotypical pentakill machine. The problem is he is the greediest champion in the game. He can't bank before 6 unless that lane is overextended to the max and bot lane has a support with alot of cc like Nautilus or sion. Shyvana is the same way interns of ganks but worse. If she has ghost, not so much but i prefer exaust for better dueling potential. She's kind of a safer pick because tank stats. She is also hell-bent on taking dragons. She is more of a teamwork version of Yi but she can still solo carry a game. Both farm alot. Neither have cc. Yi has raw damage but shyvana has on hit. Both are amazing duelists. Shyvana seems to be stronger early and Yi is a late game hyper carry and especially if he goes crit. If he goes the rageblade build, he's a little bit more vunerable but after that, he 's strong. Its just like anyone who rushes triforce because they want to buy a NS for botw XD. Also the people who play Yi and then feed their asses off are salty pieces of shit. They also play riven, vayne, fiora, and yasuo. When have a name for these people. We call them well... Bronze. They are always under the Dunning Kruger effect. A cognitive bias. Be there fall off. So who's the better low elo champion
