Whats worse: Flex or TT

Flex 5s has the absolute worst matchmaking where most games you'll see the MMR of one team at least 100+ higher than the other team based on solo queue ranks. "But it's flex, solo queue rank doesnt matter!" - it sure does when you have a plat vs silver and bronze. The higher level will always bring their map awareness, mechanics, objective focus, champ and power spike knowledge to the game while the low elo players are just there. Even if you run this in a full premade of gold for example, you'll often find yourself facing at least several diamonds or all bronze, at which the game is not fun for at least one team. Even normal games have better matchmaking

Twisted Treeline, where games are decided by 5 minutes. You thought solo queue this season is snowbally and fast? TT is even worse where comebacks are non existent and when a champ gets ahead and can 1v2 or 1v3, the game is literally over. In SR 5s if a champ is ahead you can get a pick and 1v5 them then deal with the rest of their team. You can also have some high damage carries to actually melt the fed person. In TT, you cant even kill the support if its a support & funnel comp. If its with a jungle its usually a bruiser tankfest, or has an assassin that must get so far ahead early on they can 1v3. Champ & item balance is totally thrown out the window and all patch changes affect this mode too, but literally no thought is put into how it would affect this game mode. Also in many games you'll get people who have no idea what to do and pick the worst champs for the map then hard feed, making it impossible to carry a super feeder even more than 5v5 since the feeder is 1/3 of your team and you have to take down a fed champ who can 1v3 your team. Matchmaking for the most part is also shit where their solo queue rank varies from unranked to diamond

I'm at the point where I've gotten both my accounts to gold. My goal each season is just to get ranked rewards. In the last 3 months on my other account I've been trying to do Flex to gold, but the matchmaking imbalance is unbearable. This account I've played some 3v3 on TT, and the champ balance & snowball is unbearable. Maybe just time to quit for the season?
