Most aircraft are controlled with a yoke. But why did airbus choose to use sticks to fly there aircraft? This question has been in my head for a long time. I'm a real big airbus fan, an I would like it if a real airbus pilot could answer this ,but if enyone else knows the answer you can answer to. An also are they easier to use than yokes or are they the same. Thanks alot a future captain Bryan Becker.

It's much easier to fly with a side stick, inputs are smaller and more accurate, it's only your wrist that moves and you've got a real nice clear view of the entire flightdeck.
A disadvantage is that if the copilot moves the side stick on his side the Captain 's side stick does not move at all and viceversa. If both pull in the side stick forces are added ( nose moves 2x faster).

With a fly by wire aircraft you do not need the added weight or mechanical complexity of a yoke. Just another case of economics. Even the side stick on an Airbus is could be considered too big. A small knob with a disconnect button would be sufficient.
Boeing chose to have a yoke on the 777, but it was not necessary. They probably thought it would be more readily accepted by pilots.

Just a few quick notes about the sidesticks on the Toulouse Lawnmower...
1.) the sidesticks are dependent on the displacement of the stick, rather than force applied to the stick (opposite of most FBW fighters)
b.) below 1/3 displacement of either sidestick, the inputs are algebraically summed for both sticks (usually PF + 0 = input).
iii.) beyond the displacement threshold, the second stick to move has full authority and the first stick is limited to 1/3 (remaining displacement is inneffective). I don't recall the latency involved for the second stick.
A couple of reasons for doing this are to counter a "dead-man" input, like an object jammed on the stick or, who knows, maybe a pilot slumped over the controller. Also to counter a dangerous manuever by the "other pilot".
