The controversy surrounding embryonic stem cell research is similar to that surrounding the arguments about pro choice. There are those who view conception as the beginning of life. They believe embryos to be human life. Therefore, some consider using embryonic stem cells for research as murder in much the same way as those opposed to abortion view that procedure as murder. Arguments in favor of stem cell research point out that embryos are not viable outside the mother's body. That's why they have to be frozen. Human beings can't be frozen, so how can embryos be human beings? Undoubtedly, the controversy will exist for quite some time.
They are obtained from an embryo - and the embryo does not survive. Although the embryos used will be discarded anyway (usually left over from treatments) they are still the potential start of life. This is why some people are against the use of embryonic stem cells.

Adult stem cells are useful when you want to make cells of the same tissue, as there is not much controversy about using them. Embryonic stem cells however are amazing as in the first few cell divisions they can turn into any type of cell, even a whole organ! However there is lots of ethical issues surrounding the use of these.
Stem cells are considered as undifferentiated cells. They will divide and divide forming more stem cells. The two main stem cell types are embryonic stem cells and adult stem cells. Only the embryonic stem cells can become any type of tissue. Embryonic stem cells have the potential to become any type of cell in the body. There is news as of 2015 that perhaps blindness can be cured using these embryonic stem cells.
They are not better, embryonic stem cells can become more types then adult.
The major issue involving the harvesting of embryonic stem cells is that the embryonic stem cells can cause the destruction of an embryo.
adult body cells have a function where as embryonic stem cells have no set function as of that stage. now there are some adult stem cells and those have little to no difference than embryonic stem cells

Using embryonic stem cells is unethical for many people, especially if they were only created for stem cell research.

embryonic stem cells can differentiate into more types of cells

There are people for and against using embryonic stem cells. People against embryonic stem cell use feel that an embryo is a person and can not be used for science. People for embryonic stem cell use feel that the embryo does not qualify as a human as it doesn't get past a basic division of cells, and it would be better to use it for science than discard from a fertility clinic, etc. Science is currently working on a way to bypass embryonic cell use in order to find the cure without the controversy.
The controversy surrounding stem cells arises out of the need to use stem cells from embryos which then get destroyed.
