I'm totally biased towards Android development using Gradle and kotlin.

Gradle can be a pain, but if I look at what our neighbors at the iOS team experience (constantly having to manually merge project files, not being able to simply import some libraries, ...) it's hardly a nightmare.

Specifically adding dependencies is super easy? Just specify which repo they're in (mavenCentral or Google or whatever) and add dependencies under "dependencies". When running or syncing, Gradle does the rest.
