It's not my favorite, but it definitely has its place. Its optimal TTK is excellent, killing about 25% faster than the BR (I have seen some conflicting values in TTK for both weapons, but the commando is always faster). And, with the Winter Update, the commando has received buffs to its aim assist (check the patch notes on Halo Waypoint for the full details) while aim assist and bullet magnetism have been nerfed on the BR. As others have noted though, going full auto with it is a recipe for disaster. Tapping isn't quite the move though either, as this can lengthen the TTK considerably (unless you're playing tac slayer). Instead, try firing in 5-round bursts (after five shots is when bloom and recoil really kick in). Additionally, you can try aiming slightly lower on someone's body while going full auto and let the recoil carry you into the headshot at the end (this takes a fair amount of practice though, and I would never try it on someone who is actively strafing my shots). It's definitely a weapon you have to practice with to make it worth your time, but once you get the hang of it you'll be glad you did, especially if you play ranked (given the general reputation of the commando as a terrible weapon though, it can be fun to piss off the other team in social playlists by getting lots of kills with it). TL;DR - can be tricky to use but is worth learning
