Is the texture of the tip different or is it the screen coating on the new iPad Pro? I didn't think there were 2 different replacement tip packs so the tips should be the same.I actually use the double tap feature way more than I expect to. I also prefer the texture of the 2nd get pencil. Of course the magnetic charging is WAY better in my opinion.
As for as writing goes. That's really up to the iPad. The latency on the pros makes for an incredibly smooth writing experience. I have no clue what the latency comparison between the pros and newly released iPads is. However, I didn't have any issues with my gen one pencil and gen one pro.
