>>4302560If you get a surface, make sure to get a newer moder (5/6/7) , they did update the pen technology, and it's even better after running some updates. I'd recommend looking locally for used ones, and testing them in person before paying, things to look while getting used: Install battery bar and check the battery, or run battery report(search in google for the steps) make sure the screen doesn't have bad light bleed, though it's often a thing with the Surface line. Try to get one with warranty left (simply add the device to your Microsoft account, and check the warranty, if there's issues support will send you UPS label to send yours and you get refurbished one)
Also get the latest pen, the one with 4000 levels of pressure
SP6/7 has 8th/10th gen CPU they are quad core, with 8 threads total. Its a powerhouse in tablet form factor. You should be able to get a decent deal on SP6 as it's now an older version since SP7 released in October
SP5 has 7th gen which is dual core with 4 threads, pretty underwhelming power, but does the job and runs the newest pen as it was released with it.
It's very noticeable in Photoshop, and even more in Zbrush(as it's CPU based performance, and uses all cores efficiently)
Why an Ipad Mini? You can get iPad 10.5 for like 400 euro, sometimes bundled with pen, way better size and performance, bonded glass, great display. Also the speakers on it are terrific.
Best choice would be cheaper SP6, or an iPad 10.5, check

SP's latest pen: pen itself is heavy, hover lags, but atleast it's a thing. It's decent enough for drawing, if you haven't used better.
iPad pro's pen is great, has no lag, but is heavy, has no hover functionality. Strokes kinda seem artificial as most iOS apps have too much smoothing by default.
Best app as far as performance goes on the Surface is Clip Studio Paint, smoothing doesn't lag and works great,
Adobe Fresco is great on both iPad and Surface
