Sheen nearly doubles your Q-damage early on. Hence it makes farming trivial as you start being able to oneshot em much earlier which meanse you now have a much larger time window during which you can use Q on any given minion. Which has a very similar result to doing more Q's as both make it easier to kill minions in between the attacks from your own. Basicly where without sheen you might need a lower CD because 2 minions might be low at the same time, with sheen you don't need it because you can just oneshot the first and then kill the other one at say 10% when the CD refhresses.

And if you level Q first then I don't think the extra CDR trumps sheen, I'd say they're roughly equal for farming. Sheen wins for trades though as they tend to last too short for multiple Q's anyway, though in prolonged fights CDR will eventually win, and really by late game you should've got both.

Starting with 20% CDR however, does seem usefull, but that's mostly because the early ranks have a much worse CD. At max rank you should not have much issues clearing a wave with it anyway. Ah well, both probably work and I can't tell which is definitly better.
