I keep researching this topic from several perspectives: regional availability, provided architecture, most popular use cases, VMware software versions, provided hardware configuration, and finally the price of a 3-node vSphere cluster in the Cloud.
Regional availability
The very first factor in your comparison should be if the service is available in your region? Generally speaking, each cloud vendor offers comprehensive, global availability of the service, and each vendor works on enabling the VMware service in the available regions over time.
The images below are just for illustration and are most likely already outdated (2020), please use the source links to research details on the current status.

AWS works a little differently, you need to pick the region first and then you will get the list of services available. Check out VMware Cloud on AWS in the list.

Architecture
The 3-node VMware cluster is the same VMware software in each cloud. You might find minor VMware software version differences, 6.x, 7.x, etc. on supported versions. Make sure that the cloud vendor supports the desired version, however, VMware HCX can overcome minor version differences between on-premises and cloud.
The designs and the purpose are very similar; relocate VM-based legacy monoliths quick and dirty to the cloud, and enjoy the low-latency connection to cloud-native services.
For example, Oracle Cloud has a compelling story of migrating/BYOL on-premises Oracle Standard Edition Databases to OCI Autonomous Databases while relocating the connecting VMs to Oracle VMware Solution.
Remember this, we RELOCATE VMware. Virtual Machine remains. VMware Virtual Disk Format (VMDK) remains. The software stack remains. Some of the problems remain (not the hardware maintenance) because we have just relocated our VMware deployment from the local data center to the cloud vendor’s data center.
We do relocation here. Similar to Containers. In every other “R” case, such as rehost, re-platform, etc. we stop using VMware software.

Examples of unique offerings
I am committed to understanding the unique offerings of the vendors, however, offers looks quite similar due to their nature 🙂
AWS’s offering is a VMware Service, unlike any other solution on the market. VMware offers a provisioning portal, so you will not find the VMware Cloud on AWS service on AWS Console.
Only AWS offers training and certification at the moment, but I think this will change very soon.

OCI is the only cloud that provides access to the underlying vCenter infrastructure and provides full control and responsibility for all SDDC components:

Why? Use cases.
I think if you combine ALL use cases provided by these 4 vendors you will get an idea of what and why you might relocate your VMware environment to the public cloud.
Some common points on the WHY
- You can leverage existing VMware skills in Cloud
- NSX-T network segments are pretty nice and easy ways of building a hybrid cloud
- Integrate VMware on-premises tools, skillsets, and processes with public cloud services
- You have more predictable expenses, unlike some of the public cloud(-native) services

HCX-based migration between on-premises and the cloud is really nice.
You can use VMware HCX for DR scenarios as well. In this case, there is no need for VMware SRM software (extension).
Support for additional VMware software in Cloud?
Another big question is what happens to additional VMware software you own on-premises. Can you relocate them to Cloud and continue to use them? HCX and NSX-T are mandatory parts of the solution, SRM is in most cases supported, and vRealize (now called Aria) is getting more and more support across the solutions. Below is a screenshot of how to enable additional VMware components using VMware Cloud on AWS portal.
When it comes to VDI, such as Horizon View, relocation of connections servers is not obvious, but you will find solutions that allow you to continue to use VMware VDI solutions in Cloud. Instead of or together with Azure Virtual Desktop or AWS Workspaces. For example, Microsoft offers various ways when it comes to the shared responsibility matrix.
