I have a first gen pro with the pencil 1 and find it better than an Intuos 3. I wasn't aware the later Intuos got much better, but I have not gone back to Photoshop/Wacom after getting the pencil. The comfort, form factor, and ease of use are just too good to let go.
It really is that much better of an experience. Just the ergonomics of magnetic storage and charging make a world of difference. And the pencil feels natural in your hand instead of like a stylus.
Sure they’re still not on the level of a circa 2010 Wacom Intuos – damn I loved that thing – but there’s no comparison. Pay the extra $300 to get a Pro with Pencil 2 if you can.
Now I’n thinking of getting a keyboard as well because the unimaginable is happening - my 2017 MBP feels cumbersome compared to the iPad. Only for Very Serious Work.
