I work with all the various SOCOM dudes pretty much weekly. When it comes to preparation, professionalism, and being ready to get in my aircraft, in order it’s MARSOC, Army SF, SEALs, and then Coast Guard (the MSRT dudes). PJs just intermingle so cant really say.
More to your post, SEALs aren’t dumb as much as they are just really, really good at breaking shit.
