Thanks to all the setters striving for that ideal clue.
It would be interesting to discover how "Utopia" became synonymous with a "perfect place" given that the society Thomas More described was basically the Soviet Union (although perhaps better managed) with slavery added in. Seems like the slaves would have found it pretty dystopian. Wikipedia suggests that over time utopia ("no place") became confused with eutopia ("good place"). So it goes.
To the clues: my shortlist consists of:
mattrom 7 for the nice sound-alike/charade
mathprof 8 for the nice anagram/charade
mathprof 13 - I like "first note" for UT
jono 14 for the nice "reverse in a container"
paulh 19 for the subtractive anagram and lovely yet depressing surface
aristo 20 - I liked DOH = UT + myOPIA
In the end it came down to paulh 19 vs. aristo 20, and the wordplay in aristo's clue was just too good to resist:
Doh! Short-sightedness not my idea of perfection (6)
Congrats aristo and thanks to all for playing.
