imho, none of the above, except perhaps .it as its a ccltd for a large country.
if you just want a dictionary word, there are lots ( mostly junk ) still available in the bigger extensions. e.g.
evillest.com
revving.net
excludes.org
tumours.info
all avail at time of posting.
personally, i'd say you'll probably be better off waiting until something good shows up in the drops and bid on it at auction.
