If you can, do both. With a little practice, you can solder an already-crimped wire without melting the plastic insulator on the crimp terminal. I personally prefer a 40-Watt pencil-type iron to a gun...easier for the fine work.
Being able to solder well is a handy skill to have. Either have someone competent teach you, or find a good video on YouTube.
My first two weeks of Army electronics school was soldering. Two weeks. I already had my college degree by then, so I was bored out of my mind. I was making little solder sculptures of soldiers raking the grass, picking up butts, etc. I didn't win points with my instructors with that.
