Choc beat Estrada in the first two fights and has an argument for a draw (or even a win if you squint) in the 3rd fight. Choc faced better comp across his whole career and is more accomplished. He was P4P no. 1 for a while, is a four weight champ and is campaigning for a title at 118 currently. Choc beat Estrada, Rungvisai (1st fight), Cuadras, JCM, Yaegashi, Arroyo, Viloria, Israel Gonzalez, and Yafai. I've always thought Estrada was a bit overrated honestly, he's seemed unwilling to face the best contenders or fellow champions. I find some of his matchmaking cynical and overly pragmatic at times, he goes life and death with every good fighter he faces even if he always puts on a good effort and is a crafty vet, I just don't think he'll ever surpass his Nicaraguan nemesis. Bam has a decent chance of being the first man to knock out Estrada, he's coming off a long layoff, will be rusty, he's old for the lower weights, and I just don't think he can pull this one out of the bag against someone as skilled, fast, and explosive as Bam.
