i think the op confused us all when he asked us which caliber is best. i believe he wants us to pick the best cartridge out of the three listed. it's obvious the ruger 204 is too powerful for his task. the 17 hornet is probably too under powered for the task. that leaves the 22 hornet which, thanks to machivshooter and vern humphrey, has been elevated to supreme 200 yard varmint caliber of all time. not a bad choice. i still pick the triple deuce, but it's not on the list.
if the op wants to expand the list, i would suggest the 222 remington. for a good video on this cartridge go to youtube, search "gunblue490" and watch "the great 222 remington". very informative.
