all things being equal it really wouldn't matter. The name is what you have to decide on. There are plenty of vendors selling their good on this site. Take a look at SUperBcert's site. They have top of the line Hearts & Arrows stones with very high b-scope readings and high scoring HCA marks to boot. It is all preference and priorities. Minimize what you won't be able to deal with in choosing a stone and a company and go from there. Ideal dimensions and light return should be on your list. Compare pricing between the top of the line vendors.
