Apple iPad Pro vs Microsoft Surface Pro 4, for my needs?

Please read all, and if you're a a hardcore lover of Windows or Apple, at least be fair in recommendations.

For my sweet 16 I'm not doing a party and I'm taking all the money I can and I'm going to get a new laptop replacement. Yes, I know the iPad can't technically replace my laptop, but I do have a laptop that is slow but works. I would like to totally scrap it, but if the iPad is that good I'll keep it for jobs the iPad can't do. I use Netbeans, and am a digital artist. I've had an iPad 2 and 4, and a mini. I used Procreate, and other Apple Appstore art apps. I have a Wacom Bamboo tablet with Photoshop Elements 8, and Autodesk Sketchbook Express, I also have Paint Tool Sai, but it's terribly slow. I love that program, but I can't use it with my crap laptop, that's why I wanted the Surface, so I could finally use all the programs I can't use on my laptop. I want something that will last a long time, and will still be good years from now. That also brings up another reason why I wanted to get the Surface, this iPad is just a first gen, I can almost guarantee the iPad Pro 2 will be out very soon. But again Apple products have a high resale value, you can almost sell it for the same price you bought it. Idk, I'm confused if you're curious about any information ask below and I'll edit it in, or reply to your answer.
