Keep in mind that the primary downside of soldering is that if the wire can flex at the point where the solder ends (it does wick up the wire some distance) the wire quickly fatigues and breaks right where the solder ends. That's why factory wiring harnesses with solder joints in them have stiff nylon splints on the joints to prevent flexing. A secondary problem is that if you use your own solder and it has the wrong flux core (yes, non-acid core), the combination of flux and moisture will start corroding the copper after about a year. Connectors that have a built-in solder sleeve are generally pretty good because the have the correct flux and they control the amount of solder applied so that it doesn't wick very far up the wire, and the outer connector body tube acts as a splint.
