LO Shadow Claw deals up to 91.3% under normal conditions, not enough to OHKO Marshadow after Rocks, but at -1 it's a clean OHKO. Bulky Extremekiller has a higher chance to tank the CC after SR damage and will OHKO with Shadow Claw if it survives, but both variants are still cleanly 2HKOed by Technician Force Palm.
Of course, if you really wanted to be sure that the next 'mon wouldn't fuck you over completely, you'd run Drain Punch. Solid 2HKO on even bulky Extremekiller after SR damage and you get some health back in the process.
To make a long story short, Marshadow has options and what move to run should depend on what your team needs most.
