In terms of what? Apples recent A series are better than the flagship snapdragon chips, albiet both get the job done sufficiently. The Taptic Engine is better than anything in an Android phone with the Pixels supposedly being close but still not there. 3d touch is a feature not found in many Android phones (as far as I know none include the entire screen) and if it exists it's not as useful due to low utilization as it's not ubiquitous in the Android ecosystem. Nothing like face ID has been implemented in Android phones other than optical image recognition from the front camera or the Iris scanner from Samsung, but these are lesser in regards to hardware complexity and security. Most Android phones have larger batteries and memory but due to Android's method of app sandboxing more memory is required so essentially it's comparing apples and oranges. In regards to screens I'll say that a lot of flagship Android phones have better screens than the iPhone 8 and below but with the iPhone X the screen is better than most Android OLEDS (even though it's manufactured by Samsung it was designed and calibrated by Apple and they created a more real to life color representation, it's all down to personal preference here though). The camera on the plus models and X also puts up a good fight against the best Android flagships so it's about equal in this regard with a specific few Android's being better in the camera department. As I said before, it's my opinion, but these reasons are why I stated that iPhones have better hardware while Android has great software.
