MEL Expression vs Python Node


Can I expect any performance advantage by writing a node in Python, comparing to using MEL Expression.

I would like to make some calculations in my rig but I realized that it is going to take a lot of utility nodes, I thought it would be easier just to put those calculations in form of expression. It would actually be tens of lines of code, but it seemed to be cleaner solution instead making tens of nodes and connections.

Is it worth to go one more step further and create my custom node in Python, would it be faster than expression?
