So I have a Roth IRA with Fidelity that I'm buying FSKAX in. I want to open a brokerage account as well, and ideally I would want my Roth and brokerage at the same place to make things easier. I've heard that Vanguard mutual funds like VTSAX are actually better though (please enlighten me if that's true or not), so now I'm wondering if it's worth it to move to Vanguard. I am aware I can still buy Vanguard ETFs with no fee at Fidelity as well!
On that note, I'm also wondering which one's better to buy in the first place in my Roth: mutual funds or ETFs.
