I think 
is one of the best designed champions in the game. She's rarely if ever over the top OP and always finds a nice little place to be in regardless of how the meta shifts. She's capable of playing multiple lanes (top/sup/jg/mid).
What champions do you think are almost always in a good spot?
Nami, a good example of what a generalist champ should be. She aint as oppressive as thresh nor completely usless like karma. Likely the best designed champion int the game despite being relatively old.
Both have pretty perfect design and are neither OP or useless. Being beaten by them doesnt feel bad and they reward people for perfecting the champion
(Certainly not obvious bias)
We can talk about Sion being OP all day but he never hasn't had glaring weaknesses and counter play (even when he is just plain OP numbers wise so that they don't matter...)
One of their best hybrid kits imo. Can build pure AD or pure AP or on-hit AS with drastically different outputs that are all fairly viable.
strong but not unbeatable.
Only champions I feel are "bad"
There's a few overpowered champions like 
but everything else is fine.
Edit: I read that as "most balanced"
in my opinion is the most balanced champ currently
has no mobility besides his ultimate and a few speedboosts and is one of the best duelist early but also falling off kinda hard based on what you are building on him. You can easily avoid his e and wait out his w and his q is avoidable and the champ honestly has nothing too crazy or too hard to learn about.
You can see how much stacks he has on you and you can easily back away the moment he gets 5. His q is pretty avoidable and he is very vunerable to ranged top laners because of how easily hes kited. For all his abilities he has to be close to the target and for how hard he gets kited thats pretty hard to do. When he finally gets onto you he can do alot of damage and even execute you for a reset. You have to play teamfights right and make sure darius dosent get on the adc with five stacks.
For the most part I'd say these champions always feel fair to play against and with. There are a lot of champions that are think have a good design, but the meta pushes them out of being in a good spot like 
though.
I cringe at the people saying too, especially because most people are taking him bot and abusing his poke as a "support" since they can just immediately build damage anyways. Champions that are exploited in that way are not in a good spot in my opinion. In fact, that's why I don't like a majority of the mages right now.
