The good: Similar to vanguard and fidelity on most dimensions which are also mentioned in this thread, but they’re also a bank so you can have a checking + savings account with them and all your finances are then in one place (IRA, brokerage, banking all in one). Their checking accounts offer free ATM withdrawals from any ATM world wide and when traveling they offer the actual exchange rate when withdrawing cash. Also, they have excellent customer service in my experience. Their research offering on equities is decent. Also $0 commissions on on trading equities, ETFs, most bonds and CDs.
Down sides in my opinion (YMMV): options trading is meh on Schwab, but most people shouldn’t be dabbling in options anyway. Their fully managed offerings have 0% fees, but the funds they pick internally are somewhat higher fee Schwab funds so watch out for that. You might be better off managing your own set of mutual funds/ETFs rather than going with their robo advisor if that’s what you’re after. Sometimes they do maintenance on their site on the weekends that spans beyond the midnight hours. Their mobile app is very functional but some features are slow even on an iPhone 12. Few physical branches if that’s important to you.
