It has been several years since I gave Android a try, that my experience was that the Android ecosystem (specifically the Google Play Store in the U.S.) was indeed much worse than iOS with apps distributing malware, destroying battery life and performance with background tasks, sending all your contacts off to their server, using push notifications for spam, etc. (To be clear, these things have also been problems on iOS, and my position continues to be that Apple should be even more restrictive about this stuff).
