I have an iPhone 8 (TouchID) and an iPad Pro (FaceID) and personally the multi-tasking gestures are ridiculously inferior to the home button. FaceID is nice (ApplePay, unlocking, etc) but switching to another app (multi-tasking) is painful in the "post-iPhone-X interaction model". Am I alone in this or is it a learned behavior that I simply haven't gotten over the hump yet?
EDIT: Turns out there is some nuance to iPad vs iPhone. I should also note that I'm probably referring moreso to the multi-app interface on an iPad (where you can have two apps running at the same time), which is still weird to me. Sliding left and right makes sense - get it now, but you have to remember what your last app interaction was. Also, weird downvotes?
