WY is much more private. For example, you can not type my name anywhere and find my companies in WY, but you can in NV. Also, if you need bearer shares and want to be very private, WY is the only state that currently offers this, but this is a unique situation not needed by very many people.
I like NV too, just happens to be WY is better for me now anyways.
Are those still legal and available? I've been reading that they no longer allow them?
