The Nox AT10 18K at AED 899 is Agustín Tapia's frame and the more demanding of the two. The Siux ST4 Pro at AED 789 is Franco Stupa's, slightly more forgiving, and AED 110 cheaper with four times the stock. For most club players the ST4 is the better buy; the AT10 is the better racket if your technique can use it.

The AT10
The most recognisable racket in professional padel, because Tapia has spent time at world number one holding one. The 18K refers to the density of the carbon weave on the face — tighter weave, firmer response, more energy returned on a clean strike.
That firmness is the whole character of the racket. Hit the middle and it is exceptional. Miss it and you will know immediately, in your wrist. The sweet spot sits high on the face, which suits a player who is consistent and punishes one who is not.
The ST4 Pro
Stupa's frame, and the more usable of the two at club level. Still firmly a power racket — nobody would call it forgiving — but the sweet spot is a fraction more generous and the response a fraction softer than the 18K AT10.
At AED 789 it is also the deepest stock we hold in this price range, which matters if you want the racket this week rather than whenever it comes back.
How to decide
How often do you play? Four or more times a week, and your contact is consistent: AT10. Once or twice a week: ST4.
The AT10's advantage only exists for a player who reliably finds the middle of the face. Below that, it converts into unforced errors and a sore arm, and the ST4 will produce better results for AED 110 less.
The honest caveat
Both are advanced frames. If you are in your first year, neither is right, and the AED 800 difference between these and a good beginner racket will do more for your game as court time. There is also the AT10 Pro Cup Hard 25 at AED 589 — the AT10 shape and feel at a club-level price, tagged control rather than power, and the more sensible pick for most people who like the AT10 but do not play four times a week.
