I find SMD the easiest. Using a pinecil soldering iron, or a cheap hot air station. Then through hole, because it's annoying to hold and flip the PCB around without everything falling. And finally soldering two wires is just an exercise in frustration. Helping hands or not, it's just plain annoying.
