I've actually used Ticket Tailor in the past on behalf of someone else and I loved it – in a lot of ways I think it's better than Eventbrite and more user friendly. They've been around for some time now so they know what they're doing...It's easy, intuitive, integrates with the important platforms like Strip, and it has everything you need for setting up events, selling/giving away tickets, setting up promo codes for your audience, sending out reminder emails, downloading attendance reports etc. Highly recommend it – really cool to see it here on AppSumo. :)
