The main difference is that Google Drive is essentially a traditional office suite on a traditional filesystem structure, while Notion is more like a wiki with rich document components like embedded databases.

There's a lot of overlap on what some companies might use each for, I use both for different things at work. I've found that Notion's strengths for us are when we have a collection of documents that all need to follow roughly the same structure, and we can build a mini database for them - things like blog post drafts for the company blog, RFCs, incident post-mortems, etc. On Google Drive this would be a folder of docs and a template maybe? Not searchable/sortable in the same way. Or it might be a spreadsheet with links in? But that might not be great.

I could also imagine it working well for task management in small companies/teams. I don't think Drive has a good equivalent for this.
