Why did I switch to TE?

As for me, I switched to TE because most of the changes appealed to me and made the gameplay more interesting (more playable, more enjoyable...). Regarding the new features, I haven't formed a clear opinion yet about whether monsters should gain experience or not. Regarding the differences: the main difficulty lies in the fact that not all of them are immediately obvious. I initially thought I could easily compile a list, but when I started rereading the manual, I realized that it would be too much work to write everything down.
