Using property nodes or invoke nodes for FP actions?

[J.Mamakos]

I have an idea of the differences between property nodes and invoke nodes, which was summed up quite nicely a few years ago:

Invoke Node: Invokes a method or action on a reference.

Property nodes let's you set functional or cosmetic properties of items, Invoke nodes have to do with actions.

 However, I think I'm dealing with a grey area (?) when I talk about opening (and closing) the front panel of a vi. There appear to be two ways of doing it:

And I have also seen the following example for opening or closing the FP / vi.

Is one way of doing this better than the other? Is there a reason for doing it the way shown in the second picture? And which would you recommend I settle for? Oh, and why?

It doesn't matter, either works.  I don't know of any other situations in the LabVIEW environment where a property and a method both have the same effect.
