Hi,
Thanks for the interest in our plugins. I can help out here.
Currently we just have the Business and Agency Plans.
We are working on a unlimited plan that might help out, but I do not have a timeline when it might be released or the cost for it.
For WooCommerce tickets the ticketing system is controlled on your site and the purchase of tickets is done through WooCommerce. For Eventbrite the ticket purchasing processing is done through Eventbrite and all information is managed there instead of your site. The WooCommerce Tickets system is a simplier system for tickets, while Eventbrite has many more features for event registration.
I would look at your New User Primer for WooCommerce Tickets as that shows what it can do:
https://theeventscalendar.com/knowledgebase/new-user-primer-woocommerce-tickets/
We have one for eventbrite too:
New User Primer: Eventbrite Tickets
I would also sign up for an eventbrite account as it is free and it shows you all the features they have in it and you can see what one is the best solution for you.
Let me know if you have any follow up questions.
Thanks
