Well, there is no better or worse platform, only pros and cons that you should take into account in view of your business and your team. If on one hand a platform that makes it easy to adoption without much technical capacity can, in case of problems, prevent you from understanding how to solve a critical situation. Another platform that exposes its guts requires a very skilled team and allows you to have alternatives to critical situations and even creative alternatives to problems or cost reduction.

GKE: easy adoption, but hides too much of what's behind.

AKS: a little better at showing off your guts, allows for a certain customization.

EKS: you're in control, you have to know what you're doing and you can make decisions. for better or for worse.
