Hi Rick, typically when I try to ID a plant, I find the nearest photo that I think resembles it. I give it as a suggestion for the person asking for the name. Especially with succulents, there are so many variants, and as Donald said already, sometimes too hard to distinguish them apart. So it will be up to that person asking for an ID to compare and confirm what he can actually see to what we suggest. That is why I always use "I think" or "it may." What I also do if I get a name suggestion, I research that suggestion further and read.
For this plant in question, I am looking at the bands and spots of white on the leaves. It seems the leaves are quite sharply pointed. Researching further, it seems at times both names are used for same plant, used synonymously. So there you go, it may be same plant after all.
