Vanguard is great, and for those already with them I certainly wouldn't suggest switching unless you really want more attentive service. But for those just starting out who place a value on service, Schwab offers lower expense ratios on some of the most widely used ETFs (e.g., broad US market) along with someone will always pick up the phone when you call and meet with you in person. Also, their mobile and browser platforms are slicker than Vanguard's. There's some debate about whether this is a sustainable business model for Schwab, but it's been their model for years now (I think the ER on their broad-based ETF has slowly ticked down from .06 to .03 over the past few years.) I know Vanguard is always recommended due to their ownership structure, but Schwab may be worth considering for some out there. Disclaimer: Just a happy client of both firms.
Edit to add: probably not applicable to the OP, sorry.
