Mafia Wars Wiki recommendation is to choose Yakuza for the first decision point as there are weapons like TNT, Ubjica Assault rifle, and Tanto's with around same stats and Nak Kha shotgun is with better stat overall.
But in second decison point - Triad gives a better loot, and in second decision point if you are short of 501 armor for defense monks robe is good to supply your defensive needs. There is chop shop and weapons depot which might provide a cleaver in RANDOM RARE and it will take time for armory to come, so its better to have some good defense armor from jobs.
