In my head, the levels are exactly swapped. Connecting two wires together reliably is harder than through-hole in my experience. Through-hole PCBs are actually designed for solder, so surface tension basically does your job for you. Also, with the PCB you have a solid surface to push on, whereas with two wires everything's a little bit more loose. Lastly, if you want the connection between the wires to actually be reliable, you're probably looking at splicing, which takes some more skill yet.
