Similac Neosure vs. Enfamil Enfacare?

My twins were released from the Nicu on Enfacare, however, we are running out so the NP at their piediatricition gave me several containers of Neosure and said they were essentially the same thing.  I'm doing my research and looked up reviews, and also compared ingredients but I'm still pretty nervous to switch the formulas.  The boys are 4 weeks old today.  Has anyone been in a similar situation or switched between the formulas? Thanks in advance!
