When delivering voiceovers, is it more efficient to use Dropbox or Google Drive?

I have never used Dropbox but since I have a gmail account, when I send a customer a file through email, it will default to Google Drive. I have also found WeTransfer to be a great program to send people large files for free. 

As long as you're using Fiverr, you won't have to worry about file transfers since it's all done on their interface. 

For storing my work, though, I prefer to store all of my work locally on an external SSD. 

I would rather stay on fiverr and simply use ZIP archives with folders. The delivery is done through fiverr and imho it's best practice to go through the official delivery system. In case of a dispute I would really want to rely on my delivery being on fiverr servers.

While I’ve used both Google Drive and Dropbox extensively, I find Google Drive to be a more versatile and efficient solution, especially for collaborative and organizational needs. Google Drive offers seamless integration with Google Workspace tools like Docs, Sheets, and Slides, making it ideal for real-time collaboration. Additionally, it provides 15GB of free storage, significantly more than Dropbox's 2GB free tier, which is helpful for managing larger projects without upgrading immediately.

The interface of Google Drive is intuitive, and its search functionality is powered by Google’s robust engine, making it quicker to locate specific files even within extensive folders. Furthermore, Google Drive’s pricing for higher storage tiers is more competitive, offering better value for long-term scalability. While Dropbox does excel in faster upload speeds, Google Drive’s broader features and ecosystem make it a more cohesive and organized choice for most workflows
