I have very little experience with iPads, but I absolutely hate the iPhone keyboard compared to Windows Phone/Mobile. Windows 10 is unfortunately not in the same league as its mobile predecessors.

Haven't used the Windows 10 on-screen keyboard much to be fair. I usually use the Surface keyboard (which has improved a lot circa 2017), but for prolonged work I'll attach a USB keyboard (mostly because I need an ergonomic keyboard to type).
