It's not clear what you mean exactly with "exposure". But if you only care about sharing your work, it may be better to publish it on f-droid.

Play store is the de facto marketplace for Android apps, someone looking for a new game or application will often search the Play store...

Publishing on F-Droid is good, but that presumably depends on releasing your app as open source/FOSS, which is not something every app creator will want to do.
