Health insurance is a problem. Solve it before you move to contracting.
Taxes, on the other hand, are completely skewed in favor of consulting. Look at 401k contributions, for example. The limit for your contribution is the same, but your company can contribute a lot more on top of that. And talk to your accountant about how you decide on your salary; that's an important number and it's not straightforward to decide what it is. (It's certainly not your entire income)
