I've done it before but does it now make a difference with this new upgrades?
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.
By all means, if it makes you feel better, then you can go for a clean installation. As for as technical reasons are concerned, there aren’t many that would justify this. In my experience, Macs can easily maintain optimal performance with a bit of housekeeping. If the computer feels unusually slow, then there is almost always a specific reason for it that can be addressed.
It's not necessary but if you have a hard disk you'll probably be seeing a performance decrease over the years. Also if you want the new AFPS - Apple File System coming in January (which is supposed to be better and more flexible) you have to wipe your drive and start all over again.
What are you basing this on?
Apple File System will be provided as an in-place upgrade from HFS+. You will not need to wipe the drive then either.
I have a SSD.
