I haven't experienced DL, so I won't make any blanket judgments regarding the art.
As far as these claims ...
I could go on and on. BJJ made its reputation originally through challenge matches against practitioners of other martial artists, street fighters, and generally anybody who was willing. A big selling point was the repeatedly demonstrated ability of BJJ practitioners to defeat bigger, stronger opponents. The whole blending of BJJ with other arts in MMA didn't happen until after that reputation was well established.
Personally, I've tested my BJJ against a wide range of opponents with backgrounds other than BJJ. I'm certainly not the only BJJ practitioner I know to do the same.
(Now if you wanted to complain that many
As far as the "scientifically tested" claim ... meh. It's really hard to do high-quality scientific studies on the effectiveness of any martial art due to the practical and moral difficulties in controlling all the relevant variables. However - the idea that having an art be "scientifically tested" means that practitioners of that art would win every fight? That's just silly and displays no understanding of science.

I thinK bjj,and dl, are as bad as each other, one doesn't stress test and the other doesn't teach you to actually fight someone, so both rubish, if I had to pick on it would be dl, as if you did test it, it would be a much more rounded set of skills
bjj has only been tested against other bjjers and not at all fir self defence,
