I would say its all about skill.
Ch/R has some great things like Shadow Stab, Shadow Pulse, Throw, and Remodeled body, which can be pretty deadly in sw once mastered.
But it takes some time to learn, do not expect to be great during your first ch/r sw

.
Disassembly step is nice if you need to kill lonely p/k, but usually its not that smart to use it in sw. It would leave you with too low hp.
