Apple's ipad pro/pencil is better than the previous industry best (Wacom) by a wide margin. It's more sensitive, better ergonomics (narrow diameter, not plastic), much lower initial activation pressure. Paired with a much better display in a more portable package at similar price to a Cintiq companion. Professional artists are flocking to it in droves.
From my facebook feed where I follow artists from AAA game companies: Blizzard, EA, 343, etc.
