It's largely a matter of personal risk tolerance.

For someone young and healthy who might go to the doctor once or twice per year, a HSA + high deductible plan isn't a bad proposition and is liable to save you money compared to a normal insurance policy where you're paying hundreds each month for coverage you simply don't use.

If you have regular doctor visits though, or like the cost certainty of knowing how much you're spending on healthcare even if it means spending a little more than may be strictly "necessary", the traditional plan + FSA is probably better.
