1. AWS is still vastly more popular and with way more market adoption than another other provider (by a massive margin)
2. Who cares about exciting? I want stability, with decent support, huge community and great tooling.
I think it's a case of YMMV. GCP works for some, likewise with Azure. AWS is just a good workhorse and a solid choice for just about any system.
Although I've always found it weird we have this 'us vs them' mentality with the cloud provider we end up choosing.
