When to use the static version of a method vs the non-static version

[marcusx2]

In this closed issue, @hsubox76 mentions that the static version of the method for authstatechanged and beforestatechanged should be preferred over the non-static version. Does this hold true for every non-static version of a method where a static version exists? For example, the static reload vs non-static reload. Why is the static version preferred over the non-static version, is it not just a matter of preference?

Use static methods for utility, non-static for object state.

Static Methods

Use when operation doesn't depend on object's state.
Often more performant; no need to instantiate object.

Non-Static Methods

Use when operation depends on object's state.
Allows method chaining on the instance.

In context of authstatechanged and beforestatechanged, static methods likely recommended for state-independent utility.
