Side sticks are deliberately designed to be as objectionable as possible (if certain Airbus designers had their way, they'd resemble a dog-poo in order to discourage anyone from touching it), because you're supposed to let the automatics fly the aeroplane.
A yoke is traditionally something you place on the shoulders of a poor, dumb, smelly, cud-chewing beast of burden to bind them to the tedious task of hauling a heavy, groaning agricultural vehicle across the landscape. In terms of aviation, the only difference nowadays is that the yoke is attached to the hands, rather than the shoulders.
Which leaves with the centrally mounted control stick, the preferred mechanism of skygods and helicopter monkeys. The helicopter monkeys, you will note, actually have a side-stick as well, but that's only because they like the smell of dog-poo.
Any more questions?
(Edited: for punctuation, and to point out the Yak-18T doesn't have a yoke, it has a stick with gravitas)
