As someone who has done exactly this, given up 320 command for RHS in EK, it's all a personal decision. At the end of the day, you're flying planes. Is there likely to be a covid situation in the next 3/4 years, hopefully not. You'll realistically have a widebody command there in 4/5 years at this rate. I'd wager that's more valuable than a 320 command.
But, it's a personal decision. I'm getting more money, it's a safer city for me to raise a family and from experience, my lifestyle better suits long haul.
I don't really think you can make a wrong decision here. It's a job. What's going to suit your personal life better? I don't wanna fly planes when I'm 65. And I won't be retiring early paying 50% tax in Europe.
Command is great, but it's not the golden goose. I'll sit in whatever seat they like if they pay me more.
