Question: Is there added value in having your own presentation layout and using it consistently?
Answer: Yes. If you're like me you'll never like everything about a standard layout, and you want your tools to disappear as quickly as possible when creating content.
Noticing something in your slides that you want to change (bullet type, or title colour, or whatever) is the easiest way to get distracted from doing so.

Having a standard layout for your own work means you have to spend the least amount of time worrying about the formatting.
