only EU because I think its unfair to compare across regions yet
will do an NA one too soon

Raze: SimonD4rk, Zyppaan, doma
Phoenix: Obnoks, snikk, baddyG

Will do for NA don't know other regions as well. Also, doing more than three.
Jett: Tenz, Babybay, Kehmicals, Spyder, and Wardell(Huynh on a good day too) - NA actually has few very good Jetts compared to other duelist mains
Raze: Asuna, Sinatraa, Shawn, Kehmicals, Relyks and Android - All of these guys play vastly differently some being very good with her utility like Relyks others just being aim gods like Shawn and Kehmicals
Phoenix: SicK, food, ANDRIOD and Shawn - SicK towers above the rest of the mains here but food and Shawn are still beast. I'd love to include Drone because his performances recently have not been so great partly due to TSM's bigger problems.
Reyna: Sh0t_up and thief - Disgusting players that get multi-kills after multi-kills and either one can drop 30 in any game against any team.
Yoru: nobody plays Yoru in this region
Omen: Subroza, s0m, Marved, and Nitr0/Ethan - Nothing to say much here, nitr0 is probably more than likely still a good Omen but its also interesting to see his flexibility on 100t(probably one of the most flexible players in the region). Also, I've said it before but mummAy has no place being in the controller role and z0mbs although having bad stats is still probably one of the best Omen's that know how to work with the team. Wedid will also be one of the best in this region one day.
Brimstone: supamen and all the good Omen players but recently Brim has been abandoned in NA
Viper: Poach and WeDid - Very underrated agent in this region only used on Split. Poach did very well with it on ANDBOX but WeDid is coming to his own with the agent.
Astra: nothing here yet but I have a feeling 100t or NV will show us somethign soon
Sova: sinatraa, BcJ, Hiko, and Crashies - sinatraa is the best with BcJ coming in a close second.
Breach: nitr0, Skadoodle, and Sh0t_up - Don't know how the latter two duelist mains ended up on Breach but their very good nonetheless
Skye: Crashies and Roza but NA has still yet to use Skye as effectively as Korea IMO.
Sage: SicK, food, and nitr0(stellar on a good day) - nothing to say much except that a resurgence has come in Sage use after Sentinels and 100t use of them.
Killjoy: steel, mitch, dapr, PLAYER1, and Hazed - very different playstyles again, steel being an innovator with the utility on this agent but dapr, Hazed, and PLAYER1 are just well rounded Sentinel mains
Cypher: curry, KOLER, dapr, NaturE, Steel, koosta, aproto, and PLAYER1 - the first two are great but imo need to be put on duelist asap(sgares commented on this), the best Sentinel players in the region are by far Dapr and Steel with the latter three in this list being up and coming/underrated mains
I didn't include any tier 2/3 teams that don't play tier 1 team consistently
I wouldn't put exactly what you put, but I don't really fully disagree with a lot of it except Sova. crashies is like by far the best in NA rn. Even when sinatraa was playing. Also the best sentinel players in the region are FNS/aproto, with dapr/steel coming in after those two. aproto, while not being an igl, has by far the best aim out of any sentinel player and his ability to hit headshots is disgusting. FNS is an insane strategist and IGL, he is one of the shining stars of the NV roster and while he might not have the best of aim, neither does dapr or steel.
