Any advantages to fresh install?

[Prise]

We've upgraded many of our Macs this year. Basically, all new iMacs.

It's been a few years since our last across the board upgrades, but in the past, I've always used the OS Disk to erase, partition, and do a fresh install.

This time, there is no disk. My question (aside from partitioning the HD) is better to do a fresh install of Mavericks (saved a bootable copy on usb drive which has been tested on an older Mac to ensure there's no corruption), as opposed to upgrading through the app store?

Thanks!

I recently did a fresh install of Mavericks wiping it clean, on a 2009 iMac that had been through multiple updates, prior to selling it, and the performance increase was astounding. It's with a relative and going very well. Definitely worth doing.

Yes, I also did fresh install on Mac Mini 2009 and the difference, OMG!

Do it

Have decided for fresh install, since I always partition (at least 2) my HDs. I was tempted to forgo the process, but I'm just not comfortable with a single partition, especially given the sheer size of modern HDs.
