as far as i know, tce's will not overwrite existing files, system rot would occur for any files that exist before tce's are loaded. that's a very large margin for the same disadvantages. i think tcz's are different.
wiak:
In PPR/TCE mode the tce's are loaded fresh, so the underlying system is "pristine". Of course the user's mydata.tgz then overwrites that pure system, which is hardly avoidable; except that it's pretty easy to keep backup's of previous mydata.tgz files so that you can quickly return to a known stable situation. The main thing is to keep the underlying system stable and clean; which is why such installation methods are superior to full hd installs - where actual main system rot is a constant danger.

I'm wondering if the information provided in the following two links would help with backup (and speed) issues. One concerns using tempfs to store profile info and stopping sqlite's ‘urlclassifier*.sqlite’ files growing hugely out of control, and the other concerns compressing sqlite databases to effect some (large?) speed increases in Firefox usage. I can't try either technique myself at this moment (but certainly intend doing so when I next have some time available for such, whenever that will be!):

tobiaus:
i didn't look at the second one. the first one probably won't help, as ff pretty much already runs in "tmpfs" or similar.
mcewanw:
Yes, I agree regarding tmpfs. The first link however also gives advice about using about:config to deal with urlclassifier sqlite growth excesses.
