Is AndroidTV really worth it?

I have the Android TV Mi Box. I feel that while it is convenient in some ways, it is also limiting. The new Google Play Music app is worse than the regular Android one, and I think the same goes for Youtube. And the list goes longer. The Mi Box is also stuttering for me and I am tired of that. But if I buy Shield, it will still be Android TV. Can anyone give an objective comparison with other modern Android tv boxes that run regular Android. Are they really worse?
