You are more familiar with the tools in question than I am, but
I wonder if anything would be suboptimal in the sense that you
mean it. You could argue that there may be closer to optimal ways
of intercepting an OS call for instance, but that depends on your
use-case, and I suspect is a higher level of abstraction than the
tools provide.

Single-stepping, OTOH, would not be suboptimal -- that was a
misunderstanding.
