I use three, personal computer, Android device and iOS. Honestly for me I love portability and flexibility so I don't use my personal computer all this time because it stresses me out.
I use my iOS mostly because of operations on this device is faster and more efficient but there is a let down and that is in its battery capacity, I am always on the move and I dont like walking around with a power bank so that js where my android device comes in. Android does the job but not as excellently as the iOS or my personal computer.
