If money isn't a limiting factor then the 737 job may be a good idea. Corporate you can always come back to, airline jobs you will grow too old for. Besides, at 900H on some heavier stuff every year you will build some valuable time quickly. In corporate you don't fly that much...
I know a few airline guys who have later gone corporate. I don't know many who have gone the other way (or maybe that's just because biz jets are so much more fun?
)
