Bare Minerals Vs Tru Minerals?

I have been using bare minerals for 6 months now and love it. I accidently ordered tru minerals off of ebay. It is not the best but I am thinking of mixing them with what I have left of my bare minerals. Is this a good idea? has anyone on here had any experience with tru minerals? my face looked a little blotchy when I first put it on but I think I might be able to make it work by mixing. Anyways let me know what you think.
