I have accounts at both. Simple's draw is the UI - budgeting & reporting tools. Ally's draw is the (relatively) high interest rate. Simple has one great downfall, in my opinion. They don't offer joint accounts. For me, that's a fatal flaw. I've been at Ally for a year and was at ING Direct for several years prior. I never went to the physical bank, so I was happy to trade a brick & mortar branch for a higher interest rate.
