My new employer uses Empower for our 401K. My previous employer of 10 years used Vanguard. I've always heard that Vanguard is one of the better companies with their lower fees and wide range of funds. I'm enrolled in the managed account option in both accounts, and Vanguard appears to be slightly less costly per year. Would it be wise for my to leave my money in Vanguard, or would it be beneficial to roll it over into Empower?
