I use Balanced for a non-marketplace ordering system as well as in an in-person ordering app. The Balanced dashboard is used for any account management and refunds.

I found the process of actually taking and charging a card to be a bit cumbersome with having to tokenize the card (wait for response), create the customer record (wait for response), associate the card token (wait for response), and finally create the debit (wait for response).

The tokenizing I'm absolutely fine with since it offloads the bulk of PCI compliance to Balanced, but the last three steps seemed a bit much when all I wanted to do was debit the card. I don't have any need to save a permanent customer and card record. This is a process Stripe doesn't have as far as I can tell, but I was ultimately willing to deal with it for the faster payouts.

I also like Stripe's two-factor authentication support.

And, on another note, I was a bit disappointed with both Balanced and Stripe's iOS libraries. They only support tokenizing a card. Though this is likely going to be the bulk of use by many people it meant creating everything else from scratch.
