So reading the outline, I feel like as a DACA holder, A seems to be better than B.
Pathway A is saving 55k from lottery and 23,400 for next 5 years, which means by fifth year, 392K will have a chance of green card, followed by 78K every year. It doesn't seem so bad, since that's half of current DACA number of 800k. Since this pathway is for DACA only, it might be faster than Pathway B which include other categories.
