As someone who just switched to iPad Pro 12.9 from Windows 10 tablet I would have to say, nope, not so in my opinion.
It is nice to run a full desktop but it doesn't work right switching between desktop and tablet modes. Also it slows down horribly over time as Windows tends to do as it gets more and more bloated. Some models have really noisy fans that turn on. The iPad pro does not have a fan. I was in a meeting with someone who was using one and the fan turned on. It was difficult to hear in the meeting from time to time because of the fan. It was a serious distraction.
Yes, having a desktop and tablet combined is nice, however the drawbacks is Windows 10. It's a hot mess.
