Well, not to nitpick but both of these are better examples (to me) of the same moves you show above.
And for me, it's got to be the Yair one as it's the only one that actually ended the fight and also, it was a fight he was losing with literally a second left. The perfect hail mary.
Also, for the record, the Jon Jones technique you showed where he reaches for the legs like he's going for a takedown then spins and hits the elbow is one of my favorite techniques in all of MMA, its just slick, looks beautiful and can be brutal if it lands.
