The internet hand wringing and pearl clutching about solder and fatigue is mostly baseless. There are two situations where it will matter: First is high dollar, highly engineered things. In these cases it's a non issue because you should be figuring out what will work and then doing it. That's kind of the point of expending the engineering effort. Second is some ghetto "made with what I had" abomination where an Arduino is dangling by its wires from whatever vibrating machinery it is acting as a controller for because the nature of the situation made the wasted expense of even a single zip tie inappropriate. In those cases failure doesn't really matter. If it breaks you just fix it and move on. The expansive middle ground where you care but don't care enough to waste a bunch of effort figuring out how to build it to within an inch of it's life the solution is going to be to secure the component and strain relieve the wiring near the joint well enough that it doesn't really matter how you connect things because the connection sees basically no force. That said, crimping is the superior method of fastening in 99.9% of situations.
