Leexi vs Plottr: Which is best for you?

I would like a feature where I can use one template's answers to build on the next, such as Snowflake Pro's ability to display my Step 1 tagline for Step 2's expanding it to multiple sentences, etc.

Not being able to take a book out of a series and list it individually is a problem for me, but like with all new software, these things can be added as it develops, and tech support listens.
