Personally, not professionally, I like GCP more. Feedback cycle is (used to be) faster and it feels (used to feel) less enterprisey. I also liked the idea of a new player on the market, and wanted to make sure I vote for this diversity with dollars.

I think these days GCP and AWS are more or less on par. One thing I learned the hard way: invest time into calculating your expected cloud spend. Your use case, partners you integrate with, your audience. Those impact significantly on cloud pricing.
