Just my personnal point of view after 90 games in ranked. Most of them can be really strong when played by someone who main the champ, so of course you might think that some of them are stronger than I say.
You can't have a game without one of them or perma banned
Very good on a lot of maps and drafts
Can be really useful depending on the draft and the map
Same but a bit weaker
easily countered with items or not
Never seen him played in ranked
