Are gate valves more durable or ball valves more durable? ? ?

Which one is more durable and less likely to leak? It’s not a problem if it can’t be sealed tightly; what’s concerning is leakage from the valve body itself. Behind the water meters, there used to be gate valves for each household. I want to install another one indoors. It seems that ball valves are more popular these days; should small-diameter gate valves be replaced by ball valves?
Assuming that all masses meet the standards, gate valves are more durable than ball valves, as gate valves have a mechanism for compensating for seal wear, whereas ball valves do not.
No matter how you compare them, ball valves are more durable than gate valves; gate valves are not durable to begin with.
Compared to gate valves, small household ball valves achieve a tighter seal because their sealing surfaces are soft; thus they can shut off more tightly than gate valves. When wear or leakage occurs in the spherical surface inside a ball valve, the internal seal can usually be adjusted. Therefore, I think ball valves are more durable and provide a tighter seal. However, for heating valves that are exposed to high temperatures, gate valves with hard sealing surfaces are more commonly used. I personally don’t prefer using gate valves at home as they can leak due to worn packing
Ball valves are more durable, but their price is higher than that of gate valves
Under the same environmental conditions, ball valves are more durable~~~
Choose a gate valve for durability, and a ball valve for an attractive appearance.
Ball valves are more durable for household tap water.
For the main water valve in households, all ones I’ve seen are gate valves.
It depends on the pipe diameter; those used for household connections are usually smaller, and ball valves are sufficient for them
