Overall, I do like the MT one better, especially if you're running something with Murkrow. Swarm is an excellent free attack and lets you get specifically Murkrow onto your bench, leaving room for Mentor or Great Ball to fetch something else (Holon Castform, etc). Hide Crowd can also be beneficial, allowing you to switch your active Murkrow (if you've been attaching energies onto it for whatever reason) with either another Murkrow or another Pokemon and lets you use that Murkrow to evolve into Honchkrow next turn.
As for the SW one, I'd only use it if you're running Murkrow only. Being able to evolve the turn you play it is nice, though Feint Attack is redundant as if you get into the Lv X version, he also does Feint Attack for more damange.
