In Azure, it is the storage to use, and in my view, the Blob Storage offers more, or finer-grained configuration options, than S3. So my recommendation would be to check in detail what is offered. As the Blob Storage is more or less a Microsoft exclusive product, the "interoperability" is more limited than, for example, with S3. The S3 is more widely adopted, and if you cannot exclude a migration scenario from one cloud provider to another, additional effort is needed.
It is the most appropriate tool to quickly share documents with someone you don't want to give access to your company's own online library, yet you have to share files. It's great that there's no need to create a user, nor for uploading or downloading files. Just have in mind that the documents on the link have an expiration day!
With the free version, you are limited to 2GB of file transferring. Likely if you are sending lots of files, you'll be upgrading to Plus instead.
Download links expire after a certain amount of time. It's important to download each link immediately and not forget where you left the downloaded files.
Blob storage is fairly simple, with several different options/settings that can be configured. The file explorer has enhanced its usability. Some areas could be improved, such as providing more details or stats on how many times a file has been accessed. It is an obvious choice if you're already using Azure/Entra.
WeTransfer is one of the most usable software. Incredibly smart and simple interface that I’m not sure has a comparable example that is as easy to use. The immediate ability to do what WeTransfer provides a solution for is a genius-level move from the creators. Well done, WeTransfer, well done.
WeTransfer is extremely reliable 99% of the time. There has been twice in 4 years that their service was unavailable due to server outage for several hours.
Microsoft has improved its customer service standpoint over the years. The ability to chat with an issue, get a callback, schedule a call or work with an architecture team(for free) is a huge plus. I can get mentorship and guidance on where to go with my environment without pushy sales tactics. This is very refreshing. Typically support can get me to where I need to be on the first contact, which is also nice.
I've only reached out to WeTransfer support once, but they were prompt, courteous, and answered my question. I assume that future interactions would be the same, I'm looking forward to being a long term customer.
Azure Premium Blob offers better latency than competitors. It works best with the Azure ecosystem, and competitors lack it. Azure Blob even stands out in storage durability, providing up to 16 nines. It can have various use cases that can suit all the organisation's needs. The Azure Blob solution can also be deployed on-premises.
While Dropbox does offer features that WeTransfer does not in terms of collaboration & organization, WeTransfer is the better option for simple file transfers. In my experience, WeTransfer is much faster for uploads & downloads. The premium version of WeTransfer also offers a lot of customization options that Dropbox does not.
When we've had our BETA testing programs for our products, we always used WeTransfer to send our BETA version of our products. Doing this using WeTransfer was free and we also didn't have to worry about unauthorized people later down the road downloading these versions as WeTransfer deletes the files after a small number of days.
