Feature	HSA	FSA
Who can open one	Requires HDHP enrollment	Any employer that offers it
Funds roll over	Yes — forever, fully yours	Only the IRS carryover; rest forfeited
Portable if you change jobs	Yes	No
Can be invested	Yes — grows tax-free	No
Retirement use	After 65, withdraw for anything (taxed like a 401k)	No
Mid-year contribution changes	Anytime	Only with a qualifying life event
Full election available day 1	No — accrues as contributed	Yes — entire election up front

Rule of thumb: if you qualify for an HSA (HDHP enrollment), it is almost always the stronger account — higher limit, permanent rollover, portability, and tax-free investment growth. Choose the FSA when your employer's health plan is not HDHP-qualified, or use a "limited-purpose FSA" for dental/vision alongside an HSA. You generally cannot contribute to both a standard health FSA and an HSA in the same year.
