If you do are likely to do future tenant improvements in the same buildings as previous projects, clouding on sheets is absolutely the way to go.
My office does many tenant improvements in the same buildings. When the next TI begins, we'll migrate the previous Revit project as it has all of the latest existing conditions, sheets and majority of the views already created. We merge down all model content to be "existing", purge out the old demo content that's now "temporary", and merge down all revisions to one that becomes the first new revision/submittal milestone for the new project. When clouds are on the sheets, its very easy to purge them all by opening each sheet, doing a big crossing window and deleting, so you start with a completely blank slate. When they are in views, it gets infinitely more complicated and becomes a time suck. Sheets you want to issue later will have that merged down revision that can't be uncheck and it can cause later users to chase their tail trying to find it if they're not a savvy user. I personally always cloud sheets, but after encountering this difficult issue, it cemented my stand.
I started clouding on sheets more than in view but for other reasons. For yours, why do you need to delete the actual clouds? Just delete the Revision entries from the Revision manager and all the associated clouds and tags will be gone.
