Long story short, you’re going to want to have Google Play on your device at all times, and keep it updated regularly to take advantage of the latest performance/stability improvements, bug fixes, etc. Aside from Google Play Store being a mecca of apps, games, music, movies, ebooks and more, Google Play Services is also the man behind the curtain that allows your apps and accounts to sync across multiple devices.
Yes, it’s totally possible to have a functioning Android smartphone or tablet without Google Play, but you’d really be missing out. Google Play is the foundation, the rock on which Android devices are built.
