Flying a stick is no different than a yoke.
The DA-20 is a fun aircraft. Very responsive in the air, and very efficient. It's a little faster than a 172 in cruise. They handle a crosswind landing very well. A coordinated stall is simple. The horn starts about 10kts prior and the buffett starts about 5kts prior. I prefer the DA-20 to a 172 until it's about 80 degrees otuside. After that it gets toasty in that cockpit.
The most difficult thing is taxi. It has a free castoring nosewheel so you have to use differential braking at low speeds.
