You're not going to break the gate on a maillon no matter which way you twist it, whereas it is possible on a krab (it's also pretty difficult to load a narrow maillon sideways)Are you sure? CE marked maillons (in this link) are only rated for longitudinal load, while PPE certified maillons (this link) are 55kN on the long axis but only 10kN on cross loading.
Something I didn't know until I looked up those figures is that PPE maillons are a minimum of 8mm diameter.
