Is there added value in having your own presentation layout and using it consistently? From the perspective of a Ph.D. student, how much of an added value is it to have your own presentation slides layout, that is used consistently throughout your Ph.D. conference presentations and other talks (and possibly throughout your academic career afterwards)?

Here is one such example from the Computer Science community.

This as as opposed to using existing Beamer templates with LaTeX, or built-in PowerPoint templates, or simply preparing each presentation on its own (without a specific layout).

A couple of axes I can think along:


Creating a signature layout that distinguishes one in their community
Ease of preparation of presentations (especially over time), maybe overcoming constraints with existing templates.


Note that I am not concerned with the question of content, but just design and layout.
I don't think there's any inherent value in having your own "signature" presentation layout.

Generally, you want to keep the focus on the content of your talk.  If people are noticing your layout, they are paying less attention to your science.  Would you rather stick in their minds as "the speaker with the cool result" or "the speaker with all those weird colors on their slides"?

If you really dislike the usual templates, or you can make your own workflow more efficient by creating your own, then go ahead and do it.  But I would suggest keeping your (visible) changes conservative; if your layout is radically different from what people are used to seeing, it may become distracting.
