Solder vs crimping debates are always amusing.
Both can be done very wrong and used as evidence that they are inferior methods by a tech down the road. Its always fun to point out the flaws in a previous worker's work. This is rife in likely every single manufacturing/craftsmanship related field the world over since humans could first grunt.
My opinion, is that crimping can be more idiot proof, with good tools.
It is possible to achieve visual perfection with either method yet yield a poor electrical or mechanical connection
Best possible connections, solder.
Best connections when time is money and proper tools involved and 10 years is more than good enough, crimp.
But this is my opinion, not shouted as fact. opinions shouted as fact often do the opposite their shouter intends.
Ego is a funny thing, especially when there is a keyboard style anonymity involved.
