Soldering is generally less reliable in automotive environments than crimping, since failure from vibration is far more likely. A well-made crimp will outperform a soldered joint in an environment subject to vibration, and if you are not getting satisfactory results then either you're using the wrong tool or your technique is at fault.

I'd still prefer soldering any day of the week.
I find it hard to believe that a properly soldered joint is less durable and a crimped one ??

A soldered joint is very much more likely to fracture at the connector entry, unless effective strain relief is provided.

whenever I need to crimp large terminals I usually take them to an auto electrician such as a Lucas agent and ask them to crimp them, the job is then done properly and they charge peanuts for doing the job, in fact, the last time I had them crimp a terminal they did it for free. For those who like Welsh Mountains and narrow boats have a look at my videos and photos at..

I prefer to think of soldering for electronics and crimping for Auto.

And definitely not crimping AND soldering as the heat affects the crimp greatly too on top of what Blackwolf mentioned above. (Expansion and contraction.)
It can often burn or melt insulation too.

Anything above 6mm2 you really want hydraulic or pressure such as a vice in my opinion.
The downside of a vice and press tool is it's only useable off the vehicle which you would be surpised how easy that is to do when you build a project.
Other than that it will be industrial ratchet / hydraulic and will cost plenty, I suppose you can keep it forever but realistically I don't know how often you may ever use it.
