Do you mean rendering sketches? I use photoshop directly on the surface, I do the linework in Leonardo. Do you mean CAD Rendering? I don’t do that on the Surface. No way I will inflict that pain on me. I mean, yeah, technically you can. But you don’t really want to. After all it is an Ultrabook so it has as much power as an macbook air or maybe the smaller macbook pros if you spec it out. Nowhere near workstation capabilities.
Wacoms products are clearly priced for businesses, so I would never pay for it with my personal money. It is just has a horrible bang to buck ratio, so let your company buy one for you if you can

You mean with the latter option you would save 150 bucks? Then I would take that one. I haven’t witnessed it myself but people say the display in the 2017 version with the high refresh rate gives a nice fluid feeling when sketching. And, this is my personal opinion, I never use much of my storage on iOS. I stream everything, I don’t play games and I don’t download silly apps. To this day I use a 16GB iPhone 6 and have enough space. I wouldn’t even know what to put on 64GB. But you might be different. Also you could spend the 150$ on the pencil and some case, which is both not really optional. So you can get the full package.
