I loved reading CYOA books when I was in elementary school, and I feel like the best ones could take you to drastically different places depending on your choices. I think I'd have to agree with you on simple over advanced based simply on the fact that the books I always loved had no items, no statistics, no variables. They were 100% story.
However, I do acknowledge that times change and new elements can create just as great of an experience, and in some cases better ones. Certainly some of these advanced games I've started required immense amounts of work and thought to create, and I have utmost respect for anyone who can handle that system.
Stylistic differences is one factor that really make a community of writers worth being a part of. I look forward to being a part of your community and conversing with you.
