Good Agents Pick For Each Map

Is there any base pick for each map that's really powerful?
Like you have to really pick the agent
ex: Breach on Lotus or Fracture

Icebox - Viper must pick
Fracture- Teyo
Ascent- idk tbh after wall changes but i think it must be Omen again
Pearl- Has to be either Fade/Vyse
Haven- Breach/Cypher
Split - Must be Omen/Raze or even CYPHER idk tbh
Lotus- Breach / Omen (omens a deff must pick)

Anyone but Reyna, Iso, Chamber, and Clove.

Icebox - Viper AND killjoy
Fracture- breach and maybe tejo too
Ascent- no
Pearl- maybe astra?
Haven- no
Split - maybe omen?
Lotus- no
