Aviator 35,
I went through the same, I moved to the US with a Green Card, no EK job offer and 3 kids.
PM me if you want an honest inside look.
I completely regret what I did, you have more going for you compared to my situation when i moved.
Taxes, health insurance on non legacies or high-end LCCs plus family with kids will suck you blood to the last drop if you do the regional thing.
If you are single or you wife work it is better.
