Is there a difference between any of the console/PC runs? Like are there any noticeable mechanics that are different?

Yeah the differences are pretty considerable between the versions. I cannot remember the entire list (if you ask in the Discord they will be able to provide the major ones) but the general consensus seems to be that the PS4 is the best version to run on. It is the more reliable, consistent port and all the best times have been set on it.

PC you get an autosplitter and load remover from a tooling side but I can speak from experience when I say it is not as fun to run as the PS4 version.
