All my DIN connectors in use for stranded center conductors are of the
solder type.
I use them with RG213/214/217 and with Cellflex SCF cable with 3% Ag solder.
For SCF solder less connectors are standard now.
When DIN connectors are wrenched with the right torque they are water proof.
In addition I use self vulcanizing tape and some layers of Scotch 33.
And I always use hot glue heat shrink sleeves over the cable end of the
connectors.
You can´t pull a connector off from a Cellflex or other corrugated cable.

RE: crimp-crimp PL-259's - I've never used them, only the crimp-solder
type. So I have no idea why the warning against soldering the center pin
on those connectors exists.
AFA DINs for stranded center conductor cable, to me a viable connector
type would be a single piece (with captivated center pin plus separate
crimp ring) connector with an open-on-the-end center pin (ala PL-259)
for flowing solder into.
But such an animal doesn't exist AFAIK. So we are left with the separate
center pin connectors, which I actually like like a lot for ham use.
Now as to my claim about mechanical superiority, I agree that since the
outer crimp ring is similar to the crimp PL-259's, the pull out strength
is probably similar. I guess the warm fuzzy feeling you get with DINs is
the way they conform to a precise mechanical standard. When you mate a
male DIN with a female, there is just a very robust feel to it.
