The verdict
Both are FDA-approved botulinum toxin type A and both work extremely well, the real difference is dosing units, not results. Dysport units are smaller (roughly 2.5–3 Dysport units per 1 Botox unit), so a low per-unit Dysport price is not automatically cheaper. Compare on the total price per treated area and, above all, on your injector.
"Botox vs Dysport" is the most-searched neurotoxin question, and the honest answer frustrates people who want a clear winner: for most faces, a skilled injector gets an equivalent result with either. What actually changes your outcome is who holds the needle and how well they dose you, not the brand on the vial. Where the two genuinely differ is the unit math, which is exactly where discount shops mislead.

Which should you choose?
If You want your '11s' (frown lines) softened precisely…
Botox
Its more localized spread is easy to place exactly, and nearly every injector is fluent in Botox dosing.
If You're treating a broad forehead and like faster onset…
Dysport
Its slightly wider diffusion can cover a large area with fewer injection points, and some patients see it kick in a day or two sooner.
If You're price-shopping between two clinics…
Whichever quotes the lower total per area from the more credentialed injector
A cheap per-unit Dysport price can hide a higher total because you need more units. Judge the per-area total and the injector, not the sticker.

Botox vs Dysport FAQ
Per unit, yes, but you need about 2.5–3 times as many Dysport units, so the total per treated area usually lands in the same place as Botox. Always ask for the price per area, not per unit, when you compare.
Some people report Dysport taking effect a day or two sooner, but both reach full effect within about two weeks. Onset varies more by person than by brand.
Yes, many people switch with no problem, and some alternate. A good injector will re-dose you for the new product rather than converting units blindly.
Both typically last 3–4 months. Longevity depends more on your muscle strength, dose, and metabolism than on which brand you choose.
