That was my take, the Surface can do probably everything than iPad does and vastly more. Whether you want it to or not is a personal choice, but objectively it trounces the iPad.
No, subjectively. If you don’t want the cruft and bloat of Windows, or the thicker tablet, or having to worry about malware, or a poor selection of tablet optimized apps, the iPad Pro is going to be a better choice. If you want to run Windows desktop apps on something and do drawing but don’t need lots of quality touch apps, get the Surface. The lower end Surface Pros that are priced in the same range as the iPad Pro are actually slower with a poorer screen. But keep being “objective”!
