The math on whether you are ahead with the HSA or not is non trivial, especially if you are married and neither employer offers any subsidy when you put your spouse in your plan. HSAs are often better, but it's a very unfortunate math problem, where you carry quite a bit of risk. The HSA contributions from your employer are often nowhere near enough to make it win all the time. If your employer's does, consider yourself lucky. On any given open enrollment, my household has at least 30 combinations of healthcare plans to consider, and that's ignoring dentals, visions and the like

There are some cases where an HSA is unavailable. I've had an employer not offer a high deductible plan. I've had an employer offer a high deductible plan, but the insurer not supply it in my home state.

There are cases where it doesn't make fiscal sense. One employer covered 1x premium/employee(spouses and kids were full rate).
