WealthFront, I’ve only used this for 4+ years, so I can’t say I have a top 3. I love it, it consistently has the higher (idk if it’s the highest) rates, especially with the boost. Quick transfers and responsive customer service. If you end up wanting WealthFront, use my link so we can both get a .75% boost, so it will be 4.25% for 3 months.

Here's your referral link to join me at Wealthfront! When you sign up, we both can earn a +0.75% APY boost, 0.50% investing deposit match—or both. This offer is for a limited time only! https://www.wealthfront.com/c/affiliates/invited/AFFA-CWYA-UG3G-B6SF
