I would not say that Motion behaviors sacrifice some flexibility for ease of use — I’d say that Motion behaviors sacrifice enormous flexibility for excellent ease of use.
I would also say that Ae expression trades terrible ease of use for massive flexibility. Some things that should be easy (and are easy in Motion) are pretty hard in Ae unless you have a significant base of knowledge. However, a great many things that are very hard or outright impossible in Motion are doable in Ae once you learn expressions.”
I find expressions very valuable. Yes, they can get complicated, but once you figure it out it becomes a great tool. I find linking parameters in Motion to be time consuming. There is no way that I know of to save a parameter for later use.
Expressions can be saved in a text file, usually I go with Text Edit to do this. Just simply select the expression, copy it and then paste it into a word program. When needed, it can easily be found. Also, you can copy and paste expressions to multiple layers with ease.
I do like Motion when needing to create a lower third, effect or something else to use in FCP X, one of the great things. I do love working with Motion but it is not always suited to more complex projects.
