With soldering I use a small blade screwdriver to apply a small amount of pressure on the bare wire being soldered (next to the insulation) while soldering, especially as the solder is cooling. This is to ensure that the bare wire and metal surface have very good contact and that the solder acts as a holder and sealer of the wire and metal surface (joint) and does not act as a conductor of the joint. It is not good to rely on solder as the conductor of the joint as solder is a poor conductor. I find very high eutectic solder to be best.
When done like this, soldering is way better than screws and ensures that the join is held well and sealed, so that joint oxidation (etc) does not occur. Screws can damage the wire through pressure and the screwing action and does not prevent joint oxidation. Joint oxidation can also occur with crimping. Soldering, though, is usually a bit slower but if done well, very effective.
