Depends on what you're using it for. For PvE you'd be hard pressed to find a more well rounded rocket launcher than a Hunger of Crota. It comes standard with tracking, all the best perks in the middle tree and clusterbombs for added AOE. For PvP however you want a launcher that has decent fire rate with good blast radius and velocity. You also want proximity detonation and tripod. For this Tomorrows Answer perfectly fits the bill. Comes standard with all of that and all the best middle tree perks as well with no rerolling needed. And it's on sale now by Brother Vance if you can get 7 wins in Trials.
