I would recommend to wipe your drive and do a clean install every two to three years. Probably you won't notice any major difference but it is good for the life of your drive (mostly for hdds but for ssds too!). We tend to install and uninstall many things that can corrupt our drives.
Personally I find myself more organised after the clean install cause I have to do everything from the beginning and I think differently and more efficiently every time I do that.
