Google Play vs. Samsung Galaxy Store vs. Amazon Appstore

I've published my recent app on Google Play and now I'm thinking to do it on these other app stores.

My only experience with these 3 was from about 6 years ago when I published a small children game on all of them. There are many things to account for but in the end, it got about the same number of installs on all 3. It made more money on Amazon, a bit less on Google Play, and almost none Samsung Galaxy Store. In terms of actual numbers, we're talking > 150k installs and a few hundred dollars per store.

Does anybody have some insights on how are they now comparing in terms of revenue, installs? Is it worth the time? Have you done it?
