The framing of this question is the problem. Standing all day is not the healthy version of sitting all day — it is a different set of complaints.

The short answer
Neither, exclusively. UT Southwestern lists leg pain, swelling and — for some patients — deep vein thrombosis and varicose veins among the risks of standing too much, and its guidance is to change positions, shift weight and take short walk breaks every 30 minutes. The target is alternating, not winning an argument between two static postures.
"Standing or sitting" assumes the problem is which posture you hold. It is not. The problem is holding a posture. Static loading — the same muscles working, the same tissues compressed, the same joints at the same angles for forty minutes — is the common factor in both sets of complaints.
That reframing is more useful than any comparison table, because it tells you what to optimize: not the position, the frequency of change.
Documented, and rarely mentioned by anyone selling a desk:
The comparison, in one line
Sit-stand desks are marketed as a binary switch. In practice a well-set-up workstation has four positions, and the more of them you have, the more often you move:
| Position | What it needs | Good for |
|---|---|---|
| Seated | A chair with adjustable lumbar support | Focused work, long stretches |
| Perched | A stool reaching about 30in or more | Calls, email, breaking up standing |
| Standing | Desk at elbow height, plus a mat | Reading, calls, shallow work |
| Walking | A pad, and a desk with headroom above it | Calls, reading, thinking |
You do not need all four. But going from one position to two is the single biggest improvement available, and going from two to three is the cheapest — a perch stool costs a fraction of a desk.
From the picks
The desk covers sitting and standing, the stool adds perching, and the mat makes the standing hours something you will actually repeat.
Best current-generation buy
The V2's replacement, and the one that will actually be in stock. UPLIFT puts the range at 22.6" to 48.7" — a lower floor than the V2, which matters more than the ceiling for most people — on the same 355 lb rating and 15-year warranty.

Best perch stool
Rises to 32.5", which is the height a perch actually needs to be useful at a raised desk, and the articulating pedestal keeps your hips open instead of folded. The one-year warranty is the weak spot.

Best overall standing mat
A deliberately not-flat mat: the mounds and calf shelf exist to stop you standing still, which is the actual cause of standing-desk foot pain. Backed for sixteen years.

Questions
Not as an all-day replacement. UT Southwestern names leg pain, swelling and, for some patients, DVT and varicose veins among the risks of standing too much. Alternating beats either.
Less than most people assume when they start. The ramp and the ratio are here.
It adds movement to hours that would otherwise be static, which is the thing both static postures lack. Whether it is enough exercise for your goals is a question for a doctor.
