This is in part personal preference. We have used the click-stand on heavily loaded long tours for more than 10 years and found it to be simple and reliable. The stand is affixed to our frame so always available. A cord that resides on the handle bar readily locks a brake on. We sometimes tour with others that have the twined kickstand. They must find approximate level ground and their bike has fallen more than once, but perhaps they are less careful. The click-stand does not require level ground and our bike has never fallen (knock on wood). Either stand requires something like a wide plastic bottle cap in muddy conditions to keep the stand from sinking into soft dirt. It is of course true that fixing a flat is simple with the rear tire off the ground, but that also means you must lift your heavy load off the ground each time your park the bike, and a heavy load affects the stability of the twined kickstand when bike is up. We usually have tough tires on tour so rarely a flat (more knocking on wood), but panniers/bags must come off the bike to fix a flat, which is certainly a hassle. We also use a steer-stopper to lock the front wheel in line, which is important when carrying loads on front wheel. The steer-stopper is a bit pricey, we used to use a length of webbing wheel-to-frame, but the the steer-stopper is simpler.
