I have used ConTeXt a fair amount and I like it quite a bit. I would actually say it is easier than LaTeX, in the sense that it is more discoverable. After you use it for a bit, you see that the macros are all built on each other in predictable ways, so they all tend to take the same options and achieve similar effects. In LaTeX, the answer to your questions is usually "there's a package for that," whereas in ConTeXt, the answer is often "this macro takes the same options as this other macro, so just pass them in."
What is different about ConTeXt is the prevailing attitude towards using plain TeX from it. LaTeX really seems to consider plain TeX quite unsafe. I suspect this is because it is hard to build a resilient declarative system on highly weird and procedural TeX. ConTeXt, on the other hand, kind of encourages you to use TeX directly. So that led me to learning more about plain TeX, which now seems much less scary to me than when I was using LaTeX.
