The big gotcha for Vue2 was the performance when you wanted to display a list of like 10,000 things. I like to tinker with data and a lot of my day is spent on an sql prompt inside of emacs watching results sets of 1,000 rows or 50 columns just fly by so I can search them visually. Having to remember to "freeze" things for performance or create simpler "views" of the model I'm playing with is sometimes jarring.

This tripped me up recently too. Somehow I'd got it in my head that Vue (2) would selectively re-render sub-trees within a given component if no dependencies within the tree had changed. I had a table functioning as a datasheet (not even that big—about 20 columns by 100 rows) that was absolutely chugging and I couldn't work out why, because nothing within the table was changing very often. Extracted it to its own component and all the performance issues went away.
