Which Democratic held US Senate seat up for re-election in 2022 is considered the most vulnerable?

AZ(Kelly-D),GA(Warnock-D), or NV(Cortez Masto-D)?

I choose NV.
Top Tier Republican nominee - Adam Laxalt who has ran for statewide office twice, grandson of a US Senator and a son of a US Senator.
AZ- if Mark Brnovich-R is the Republican nominee- two term state Attorney General. If Blake Masters-R is the Republican Nominee, AZ moves into the Lean Democratic column.
GA-Warnock(D-GA) wins re-election due to Stacey Abrams coattails and Herschel Walker’s gaffes.
