I prefer functional. Procedural is not restrained enough and allows for mutable global state. This can go off the rails when multiple people are in the code.
Functional stresses composition so functions should stay small, and ADTs allow for all effects (errors!) to be represented. Strong typing helps reduce the number of tests I need to write, as well.
