You get a brokerage, you can have your retirement accounts there, you get free checks, debit card with free ATM access, software that's best in class for finance (even if it's still mediocre compared to consumer software).
You can configure automatic bill pay, automatic investments, free money wires to external banks to pay rents, no fees for anything really, no useless savings account or restrictions.
Even the phone support is better than any other financial institution I've ever had to deal with.
Zero fee total market index funds, no fees really for anything.
I think the only reason people don't use them is because they don't know it's an option and they use whatever bank their parents used.
