Best and Worst Ultimate ability

What is the worst and Best Ultimate ability for each category of Agents :-
For me

Duelist
Best :- Jett / raze
Worst :- Reyna

Sentinal :-
Best :- Killjoy
Worst : Cypher (cypher's ultimate is weakest compared to other Sentinal but still decent though)

Controller :-
Best :- Viper / Harbour
Worst :- Omen ( Pros only use Omen's ult to get info while cosmic Divide can be used to retakes )

Initiator :-
Best :- Skye / Breech
Worst :- Gekko (Gekko has to be the worst Initiator agent in the game )

Edit :- To all the People saying u I put Skye ult in best category it's just because the ult is more versatile, it can be used to open a site and To retake as it gives position of the enemies . Also Skye Ult is best for mid rounding as It can Get information is u are pushing in a stack or a free site .
Also I am only taking about ults in VCT matches

WOWOW skye in best is crazy

Skye > Kayo? ayoo

All the initiator ultimates are so strong, none of them can be considered bad. Sova, kayo, breach and fade ult are really important and valuable, but even skye and gekko have good ults. I think chamber ult is worse than cypher ult for the sentinel agents.

Duelist
