Don't despair. Despite common perception, most AWS products are half-baked and clunky. (I don't have much experience with other Amazon products.) A while ago when GCP appeared in the scene, the team I was in performed a series of tests to evaluate it. In all our tests, GCP came out ahead of AWS. On top of that, their documentation and UI was better and prices were lower. That's part of how Google managed to get a foothold in the cloud services space.
AWS premium support doesn't help much when you are fighting fire because the first line support staff is clueless. It will take you days to reach a person who can actually help you.
IMHO, if you are offering a standalone product, you can always do better than Amazon (AWS). Whether you can beat them depends on variables other than the quality of your product.
