For me, the answer is both no and yes. If I use the same care in prep, stretching and technique with a NEW disposable cartrige, I get a shave of equal quality to what I get with my straight. The second shave with the cartrige is also quite good, but by the third, the edge has deteriorated to the point where the quality of the shave declines significantly. Further use results in a continuing decline in both closeness and comfort.

I refresh the edge of my straigth razors by stropping before each shave. I also have more than one razor so I do let the edge rest between shaves. I suppose I could use multiple disposables to let the blades rest, but I cannot for the life of me figure out how to strop one.
