Have the two-legged kickstand on our tandem - and I love it. I had the framebuilder braze a plate under the chainstays as a kickstand mount. This way it isn't clamped to the chainstays and can't ruin the paint or rotate into the crankarm or wheel. The bike stands up while I release the front brakes and remove the front wheel in order to put it on the car. It stands there while I put the panniers on it. I can turn the cranks and adjust the derailleurs without a workstand. It stands there while I clean it. I don't have to scuff up the handlebar tape or brake hoods leaning it against a wall. It's so convenient that I just don't understand the prejudice against them. The only downside I can see is the added weight; but if I cared that much about weight, I would remove the drum brake, fenders and rack first.
