Just downgraded Delta AmEx Plat to Blue

Joining the trickle of people who committed to leaving the Delta ecosystem after last year’s drastic changes. Got a 15k pt or $150 statement credit for $2k spend retention offer. Not nearly enough to justify only 1/4 RUC upgrades going through and an inability to redeem the companion cert. So now I’m Blue and short haul commuting via JetBlue for nearly 40% less in cash or point value. How are other folks handling their downgrade (or outright closure) calculation?
