Rg316 or 316ds are far better and more rugged cables.
ITs about ability to solder and not have it melt (rg174 is polyethylene and melts!).
When I use small coax where one end is soldered PTFE (316 and related) is
far easier to use.
Its also tougher as the PTFE is less likely break and the internal wire is often
silver over steel those some are silver over copper. Most crimp connectors are
sized for RG316 and the 316DS usualy uses a slightly different connector.
For test cables the larger dual or triple braid PTFE cables are also often used.
