Sigh, this again. I'm just a hobbyist learning artist, I got surface pro 4 core m model, I must say that is the best Microsoft has to offer, but I have had constant bugs, terrible support and it's touchscreen died. I really was about to opt for the iPad pro last time (2015) but the cost of apple pencil just made me chose the Surface, but know it is equal. I don't care about latency as much in the pen, but I heard this time it is almost the same in both devices, both have tilt, surface has edge of professional programs, iPad has edge of convenient programs. Both will cost identical with the pens, I'd prolly go for 128gb on the iPad and i5 on the Surface. There is something called Astropad on the iPad that just sold me, it essentially makes the iPad a cintiq, but it only works on Mac, I do not own a Mac, hackintosh maybe? I also have the option to stick with my current device and just get the new pen since that works.
