Resistance of the soldered connection will be consistently lower compared to terminals, also terminals with screws, especially in WW II quality, will oxidise quickly in a wet environment and thus the resistance will go up over time. Plus you get a very nice visual feedback by the self-soldering joints. Terminals look all the same - you need tools to control the quality of the electrical connection. So for longer lines with several joints that are needed for more than a few days, I‘ll definitely put my money on the soldering team.
