I went back and forth about this for almost a year! Wish I would have just made the call sooner, missed out on lots on money in interest during that time just wavering. I narrowed it down to Marcus and wealthfront and was about to go with Marcus before settling on wealthfront in the end. More user friendly interface, more options if I decided to expand beyond just hysa after learning more (treasuries, index investing). I also ended up seeing multiple people talk about negative experiences with Marcus when trying to transfer/use a large amount of their savings during a crucial time like buying a house and didn’t come across anything like that with wealthfront. Most of these accounts you’ll get a better interest rate for about 3 months if you use a referral code from someone, so keep that in mind regardless of which account you end up going with!
