I checked some private healthcare insurance where I live, and the difference in cost between these plans was in fact only $800.
And it's not "my choice." That's mathematically how you evaluate different alternatives. All other things being equal, would you not value a house with a pool higher than one that doesn't?
I didn't do that calculation on a "for me" basis: I looked at the generally advertised cost. Paying in advance is cheaper for anyone taking out a policy.
Anecdotally, every time I run the numbers for my family the high deductible plan comes out ahead so I view an offer without one as less appealing. Though most employers offer both.
Sure, the tax advantage is nice, but it doesn't make up for expecting to be paying $2000 in visits over the course of a year, then (for whatever unexpected reason) paying half that—the extra $1000 just goes away, and with it the tax savings you would have made over years of effective use.
HSA is basically a retirement account that lets you early withdraw for healthcare related expenses. There is no 'lose it'.

Edit: And to be clear, that's not "lose it if you leave the job"; it's "lose it at the end of the year."
Of course, leave it up to the IRS to take something that should be a good thing, and put rules around it that make it hard to use.
It is the best type of retirement account when used that way and I think it’s worth at least $1K/yr today assuming you’ll be able to drain it before it turns into an IRA.
