Help needed to decide if I should use AfterUpdate or Exit on my UserForm Combobox

[RunTime91]

Greetings Experts!

I am triggering code based on the EU's selection in a ComboBox.
I just need some guidance on which event to use between AfterUpdate or Exit; or does it matter?
Right now I'm using Exit but I've never been crazy about seeing the 'ByVal Cancel...' after the event.

I'm imagining since both events exist that there is a difference. Yes, I've read what the internet has to say.
Now I'm asking the experts.

Effectively, what I'm doing is setting the formats, Labels and the enabled features for textbox's based on what the EU selects in the ComboBox
And I want those changes to take effect once the EU exits (tabs or clicks out of the ComboBox)

As Always ~ Thank You for the education ~

Often times I find it helpful to review the Microsoft documentation refresh myself about what each event does, then perhaps conduct some testing with each method to see what works best for my application.
