The Cybex Sirona S boasts a rear-facing weight limit range of 4 to 50 pounds and a height limit of 49 inches. The Evenflo Gold Revolve 360 offers a rear-facing weight limit of up to 40 pounds and 40 inches. Therefore, if you need a car seat with the capability to accommodate larger children in the rear-facing position, Cybex Sirona S is the better choice.
For forward-facing weight and height limits, both car seats offer very similar capabilities with up to 65 pounds for weight and up to 49 inches in height.
The Cybex Sirona S does not have a high back booster option. The Evenflo Gold Revolve 360 has one from 40 to 120 pounds and 44 to 57 inches in height. Thus, if you plan on using your car seat as a high back booster too, then you should go for the Evenflo Gold Revolve 360.

Consider narrowing down your options by focusing on those made with EPP or EPS foam for impact management. Both materials meet government safety regulations, but EPP foam is more elastic and less brittle than EPS foam, making it better at withstanding multiple impacts and regaining its shape.
Keep in mind that any seat involved in an accident should be replaced, regardless of the foam type.
