The answer is often both, but only if you truly need both tasks.
PDF maintains a fixed layout for external sharing without distortion on the recipient's device. A PowerPoint or Keynote file allows the team to update data and add pages without returning to the studio. If you need to do both, get both formats from the start.
PDF and PowerPoint or Keynote files do not compete with each other. They solve two separate problems: one is for stable sending, the other for flexible editing. The decision on what to receive depends on what you need to do with the document after receiving it, not on the habits or defaults of the studio.
PDF was created to fix layouts for printing and distribution. Whether the recipient uses Windows or Mac, any font, large or small screen, the layout does not change. This is an advantage when sending documents to investors or partners, as a broken layout can damage credibility. However, because of its fixed nature, PDF is not a tool for working or editing.
A PowerPoint or Keynote file is a working document. The team can add slides, update data, and adjust content without needing the studio involved. This format allows you to manage the document independently after the project ends.
PDF was designed to fix layouts for printing and distribution, not for long reading on screen or editing. This is an advantage when sending out but a disadvantage when flexibility is needed.

Sinh Vũ defaults to delivering both: a PDF version for distribution and an editable PowerPoint or Keynote file. Before delivery, Sinh Vũ checks the soft file to confirm the layout displays correctly, not just exporting and sending it.
The operational perspective is that you should not depend on the studio for each data change or additional page. The soft files are included in the deliverables, not as an additional purchase item. However, only accept what you truly use: if the document is sent only once and no one needs to edit it later, a PDF is sufficient, no need for additional soft files.
A point that few ask but should know: if the document has accessibility requirements, such as serving visually impaired individuals or submitting in a tender with specific regulations, the PDF needs to be tagged structurally according to PDF/UA standards (ISO 14289). This is a specific technical requirement that should be confirmed with the studio at the start of the project if you fall into this category.

There is no issue if the document is sent only once and no one needs to make changes later. But if the data changes frequently or the sales team needs additional pages, you will have to return to the studio for each small revision. This takes more time and money in the long run than receiving additional soft files from the start.
No. A PowerPoint file opened on someone else's machine may misalign if they do not have the correct fonts installed, and the recipient may accidentally alter the content. For documents sent out to investors or partners, use a locked PDF version.
The reason is often a missing font: your device may not have the font that the studio used in the design. When receiving the deliverables, ask the studio to send the font file or installation instructions, and try opening the file before the project ends to confirm it displays correctly.
